Hi I have a infinite loop that wait an event set in a gpio interrupt bywhile(1){UTIL_SEQ_WaitEvt()...}It works.Now, I want have a timer after this so, if the interrupt doen't fire for some second, I want to exec a callback function.I added after UTILS_SEQ_WaitEvt  HW_TS_Start(idTmr,TMOUT);The timer and callback function was created before the loop.After the timer Start function , the interrupt works but the WaitEvent doesn't fire anymore. Someone can help me?Thanks

Hello, I'm trying to configure my NUCLEO-U575ZI-Q to read multiple channels of ADC at once. I will describe the settings in the following and then raise my questions:1- I use IN1 and IN2 on ADC4 which corresponds to PC0 and PC1 on the EVB2- I set scan conversion mode to Forward (which I guess it means read first PC0 and then PC1 right?)3- Continuous conversion mode is disabled4- DMA continuous requests is Enabled (the strange part is that this option doesn't exist for ADC1. Will appreciate if someone can explain the reason and the meaning of it)5- End of Conversion selection is set to End of Sequence of conversion (not single conversion) which should mean the EoC is True only after the two channels are converted (right?)6- SamplingTime common 1&2 are set to 7.5 (I'm not sure why there are two)7- Trigger Frequency is set to Low8- I'd like to use Regular Conversion Launched by SW at the beginning and later use a Timer to automate this process. But this means that every time I ne

Hello Everyone, I am using STM32H573. Do we need to connect RS232 to UART transceiver or can we directly interface Rs232 signals with UART?

Hi all,I'm experimenting on an STM32F723disco board, trying out some audio DSP. I seem to be getting abysmal processing speed.So as a first sanity check I did a simple nop timing test:Turn on a GPIO pin, do 50 nops, turn the GPIO pin off. (By 50 nops, I mean 50 lines saying asm("nop") )Turn the GPIO pin on again, do 100 nops, turn the GPIO pin off.This gives me two pairs of pulses, the difference in length of which should correspond to the 50 extra nops the second time around. Result: it seems a nop takes around 9.6ns, which is two clock cycles.Curiously, ART wasn't enabled, but setting the ARTEN bit had no impact anyway.I must be doing something terribly wrong.Cheers,B.

Hello, Recently, a STM32CubeMP13 Package has beed added by ST ( here on the wiki, here on github). I tried to use external loader with STM32MP135F-DK board, the same board used in the wiki. First, I used SD external loader, with UART and USB connection, following instruction described here. For USB connection, CubeProgrammer gave me these errors : With UART connection, flashin service work, but when I change boot mode for microSD card and reset, I get nothing on serial port and red led LD4 is blinking. The expected operation, as indicated in the wiki, is to have the blue LED flashing and a message via the serial link. I also tried to flash the program in SNOR memory. With UART connection, I have the same result except for red led, who is not blinking but turned on. With USB connection, I have the same error as with the sd card.I use STM32CubeProgrammer 2.15 and I was careful to choose the right boot modeSince I'm using the same development board

We want to do parallel communication. How can we do parallel communication with the following microcontroller?Is it possible to perform parallel communication by using I2C function?[IDE]STM32CubeIDE 1.14.0[MCU] STM32F412VGT6

Hello,I'm trying to do SPI communication with an ADE1201 chip through an STM32H753VIT6 chip.The maximum allowed frequency of the ADE1201 is 10MHZ, so I set the SPI to communicate with the MCU at 6.25MHZ.(The clock for SPI communication is 25MHZ, and I set the PRESCALER value to 4).However, a strange phenomenon was observed. I observed through the scope that the SPI CS signal should be 0 continuously, but it turns to 1 in the middle.(See attached photo).However, if I set the PRESCALER value to 8, the CS signal is continuously output as 0. What could be the cause? And how can I solve this?Could this be due to the usage of HAL_SPI_TransmitReceive function?

I'm working on a project to use L9502 for PWM output diagnostic. But we can't be sure how to config the Frame Counter bit in SPI message. Is it need to update the frame counter every time, or it just need to update it in consecutive frames? And for the consecutive frames, should we follow the SPI interframe delay electrical characteristics? Thanks for your help!

Hello,We have designed our FMC interface using NOR Mode B multiplexed AD-Bus.Checking the actual Revision 6https://www.st.com/resource/en/reference_manual/DM00366355.pdfreference manual this is not allowed, see Ch. 25.8.4 (Pg1365):If the extended mode is enabled (EXTMOD bit is set in the FMC_BCRx register), up to four extended modes (A, B, C and D) are available. It is possible to mix A, B, C and D modes for read and write operations. For example, read operation can be performed in mode A and write in mode B. The extended mode is not compatible with the muxed mode (EXTMOD bit must be kept cleared in muxed mode). This has changed from the time we have developed our interface. At that time the document had Revision 4. And this chapter does not contain the restriction in the last sentence as outlined above. Can somebody explain the reason for the change?What can happen if we keep this settings for the fmc2 the way we have designed it? Thanks 

Currently I am trying to interface with a LM75A temperature sensor using the STM32F446RE nucleo board.From the datasheet of the LM75A, I gathered that the sensor, returns a temperature measurement without any configuration.So I tried to simply hook up the LM75A (with floating Address Pins) and connecting it to the I2C1 port on the STM32.Addressing the slave on the given default address of 0x48h The code below returns HAL_BUSY, and locks up. Since I do not have a Logic Analyzer at home, I cannot manually debug what is going on. #include "COM_Driver.h" #include "LM75A_Driver.h" #include <string.h> int main(){ LM75_Init(); COM_Init(); uint8_t data[2]; float temperature; char tes[8]; while (1) { HAL_StatusTypeDef status = LM75_ReadReg(LM75A_ADDRESS, LM75_TEMP_REG, data, 2); if (status != HAL_OK) { // Handle I2C communication error continue; // Skip to the next iteration of the loop } temperature = (float)((data[0] << 8) | data[1])

Hello! I’m using Keil uVision to program the stm32f103c8t6 (blue pill). I’m having problems with the loops when trying to turn on and off the LED on pin 13 port C. I just wanted to use a loop to generate a delay without needing to use timers, since I wanted to generate a simple program. But when I download it to the board, the LED stays on instead of turning on and off, regardless of the wait value I put in. I would appreciate it if you could tell me if I’m doing something wrong and indicate the solution. Thanks in advance. The code is as follows: #include "stm32f10x.h" #define RCC_CR (*((volatile uint32_t *)0x40021000)) #define RCC_APB2ENR     (*((volatile uint32_t *)0x40021018)) #define RCC_CFGR      (*((volatile uint32_t *)0x40021004))  #define GPIOC_CRH (*((volatile uint32_t *)0x40011004)) #define GPIOC_ODR (*((volatile uint32_t *)0x4001100C)) int main(){RCC_CR |= 0x1;  while( !(RCC_CR & 0x2) ){}&nb

Hi all,I'm trying to use Timer16 to create a 50Hz timer to save files in the SD card. I managed to make the timer work blinking a LED, but when I put the code to save it only saves one line. Here's the logic:First I create a file  and initiate the timer in the USER CODE BEGIN 2 (I want to state that if I start the timer after the SD has been created, it doesn't work (don't know why)).//TimerHAL_TIM_Base_Start_IT(&htim16);//Mount SDfresult = f_mount(&fs, "", 0);f_getfree("", &fre_clust, &pfs);total = (uint32_t)((pfs->n_fatent - 2) * pfs->csize * 0.5);bufclear();free_space = (uint32_t)(fre_clust * pfs->csize * 0.5);//Open file to read / create it if it doesn't exist//fresult = f_open(&fil, file_name, FA_OPEN_ALWAYS | FA_WRITE);fresult = f_open(&fil, "testeTimer2.csv", FA_OPEN_ALWAYS | FA_WRITE);f_gets(buffer, f_size(&fil), &fil);fresult = f_lseek(&fil, f_size(&fil));fresult = f_puts("cabecalho,numero,tempo,ticks,ano,mes,dia,hora,minut

My project to have USB VCP UART working on NUCLEO-U575 as well as NUCLEO-U5A5 boards (via a compile macro).Use the USB-C USR USB connection as a USB based UART (COM port on host): any baud rate as supported by USB speed (FS vs. HS). There is a second UART via the ST-LINK (baud rate: 1843200): so, you have two USB based UARTs - in parallel.The project is here:https://github.com/tjaekel/NUCLEO-U5A5JZ-Q_QSPI It provides already a command line (shell), to interpret the entered line as a command to execute. Extend the list of commands - if you like. Enter "help" to see list of implemented commands.It uses also ADC to measure and display core voltage (VREF, VBAT) and chip temperature (use it as example how to use ADC1 for internal measurements). Enter "sysinfo" to see the values.It demonstrates how to handle the differences between a U575 and a U5A5 chip, which are:U575 has (just) an integrated USB OTG FS PHY (running in FS mode)U5A5 has (just) an integrated USB OTG HS PHY - my preferen

I'm trying to read i2s data on F401 from a dummy master device with slow clock rate.The problem is that it only reads the first channel correctly, rest is gibberish, based on logic analyzer the rest of data is there. so I generate this simple test data with bitbang going into F401, content should be: 0001 0203, 0405 0607, 0809 0A0B  (only last is displayed)zoomed out: what I read in F401 is:It starts to receive from second frame, that's fine, but why is the rest gibberish if data seems right?Weird part is that during every test I get the same invalid values, like if it desyncronises everytime the same way. #define DMA_BUFF_LEN 8 static volatile int32_t dmaRxBuf[DMA_BUFF_LEN+1]; static I2S_HandleTypeDef hi2s2; __HAL_RCC_SPI2_CLK_ENABLE(); hi2s2.Instance = SPI2; hi2s2.Init.Mode = I2S_MODE_SLAVE_RX; hi2s2.Init.Standard = I2S_STANDARD_PHILIPS; hi2s2.Init.DataFormat = I2S_DATAFORMAT_32B; hi2s2.Init.MCLKOutput = I2S_MCLKOUTPUT_DISABLE; hi2s2.Init.AudioFreq = I2S_AUDIOFR

Hi all, I am implementing the following GitHub code to initiate sensor fusion in the LSM6DSV16X sensor chip. The board will communicate via UART however there seems to be an issue reading and writing to registers via the HAL driver functions provided. I am using the NUCLEO-F411RE as recommended in the code with the ISK4A1 expansion board. If anyone knows what might be wrong with the HAL memory read and memory write functions please let me know. Could it be an incorrect I2C address being called? Or is there something wrong with the combination of boards I am using? GitHub Link: https://github.com/STMicroelectronics/STMems_Standard_C_drivers/blob/master/README.mdThe attached files are the C code files which I am trying to use. Thank you in advance! 

Hello,once again the same question - Custom Widget.Everything I do now I do with a Custom Container, but I'm wondering how to do it with a Custom Widget.Can an existing widget be used in a custom widget? For example, can I draw a circle and a line under the circle and have it in its own widget?I'm trying to look at the sample QR Code example, but it's broken in the current version of touchgfx (at least I can't compile the result).Is there any sample code for a custom widget besides the mentioned QR Code?

Hello,I am using a CR95HF NFC transceiver and want to have the option to select one of two antennas in my design.I had protoyped this idea with some Skyworks RF mulitplexers and a CR95HF development kit, essentially tapping into where the antenna joins to feed it through the mux. I'm using two off-the-shelf NFC antennas at the other side of the muxes.Unfortunately this hasn't worked. I'm not sure if I'm doing something wrong in my setup, or if the two new antennas simply are not tuned correctly to work with the existing dev kit.Thoughts and insight appreciated!

Hello,I have implemented LIS2DW12 driver into our product and self-test procedure according to the AN5038 (as a minor difference, instead of waiting 100ms in the process, I use 5 newest samples from FIFO after FIFO gets filled with 30 samples, i.e. discard 25 first samples and then take average over 5 last).After some testing we found that 99% of the time the self-test reports success, but there are some static positions where the self-test could fail.From what I have found, failure happens only on the third axis (z) and only on one test polarity at once (when retesting the same position on different test polarity, then it passes). At the same time, when I place the sensor in mirrored position, then I get a pass on previously failing polarity test and at the same time get failure on other polarity (still, the same axis).The problem is repeatable on multiple units and the output pattern is the same. The problem is repeatable with different sampling frequencies (tested 200Hz and 50H

My MX Repository has grown to more than 40 GB which is not exactly fun on the SSD of my MacBook. So I was wondering what made it so big.There seem to be all the zip files of all installed firmware packages. Does CubeMX/CubeIDE ever use them again?And what about the older revisions of the firmware packages? Is it safe to remove them?
