Posted on May 28, 2018 at 09:05   Im trying to catch data from the unknown device, this device has data and clock. I decided to make my stm32 as spi slave and catch the data as recevier.And im struggling with it. I have this data flow which i want to catch:  Clock is yellow and green is data.  I need only 16bytes from it, when data line goes low, we can see this 16bytes:  And there is the speed of the clock, as you can see its around 1.5us each clock pulse. So what i have to do is configure spi with HAL, i toolk SPI1(PA5 - CLOCK, PA7- DATA) cuz it has more powerful MHZ, chose spi mode ''RECEIVE ONLY SLAVE'', HARDWARE NSS SIGNAL: DISABLED. And here is my spi1 config: static void MX_SPI1_Init(void) { /* SPI1 parameter configuration*/ hspi1.Instance = SPI1; hspi1.Init.Mode = SPI_MODE_SLAVE; hspi1.Init.Direction = SPI_DIRECTION_2LINES_RXONLY; hspi1.Init.DataSize = SPI_DATASIZE_8BIT; hspi1.Init.CLKPolarity = SPI_POLARITY_HIGH; hspi1.Init.CLKPhase = SPI_PHASE_1EDGE; hspi1.Init.NSS = SPI_NSS_

Posted on January 17, 2018 at 09:03The STM8 and the STM32 variant of the CubeMX seems to be using the same recent file list.This could be confusing because the files are not compatible vice versa:Please separate the list somehow (filter for ioc/ioc8 files for e.g.)#bug-report #stm8cubemx #stm32cubemx #cubemx #bug

Posted on May 30, 2018 at 13:38Hi everyone,I'm sorry to push this old thread but I'm facing problems using the LL drivers and initializing the ADC.The function LL_ADC_Init(ADC_TypeDef *ADCx, LL_ADC_InitTypeDef *ADC_InitStruct) doesn't set the CKMODE in ADC_CFGR2.Does anyone else also have this problem?Best regards

Posted on June 07, 2018 at 12:16Hello,I am using the code supplied by ST for the X-NUCLEO-NFC05A1, with a different processor (STM32L031) than on the demo NUCLEO board, to control the ST25R3911 with ISO15693.This code comes from the example STM32CubeExpansion_NFC5_v1.0.0.Seems I have something wrong because I always get the error ERR_IO when trying to detect a tag.Comments in code say: /*******************************************************************************/ /* REMARK: Silicon workaround ST25R3911 Errata &sharpTBD */ /* ST25R3911 may indicate RXE without RXS previously, this happens upon some */ /* noise or incomplete byte frames with less than 4 bits */ /*******************************************************************************/I haven't been able to figure out why I get this error so far, although if I plug directly the demo board processor to my RFID reader board with SPI bus + IRQ signal, everything works fine.With my board, RFAL initialisation works fin

Posted on June 06, 2018 at 12:45Hello.I wanna ask that I don't know about the filename of IBIS about STM32L1.I download it from the product page, it looks like:I don't understand what ''429/427/436'' is.I googled that it's about STM32F1XXX or other, and the ''XXX'' is the number.Are they different in simlation?Tks for your help.#stm32l1 #ibis-models #ibis #stm32l

Posted on June 01, 2018 at 15:36 Hi guys, I'm having some troubles understanding the behavior of the ST GPIO on start-up, specifically PA3 on STM32L496VE micro. Background: I'm trying to program/flash a SiLabs BT121 (Bluetooth module) chip and have the following configuration on my board: I'm using a dev kit offered by SiLabs, DKBT, to program the BT The dev kit acts as a USB to UART converter to interface the UART on the BT On the MPU host side I have PA0 to PA3 configured as UART as follows: When programming the BT121 the datasheet advises to keep the host MPU in reset state to keep lines floating. Here's my issue: whenever I try to program the BT121 w/ a MPU that's erased/not programmed it fails. If I keep the MPU in reset manually (pulled the NRST pin low) thenprogrammingis successful. Following capture is for the TX (pink), RX (green), RESET (yellow) and BOOT0 (blue) pins on the initial reset dip that puts the BT121 in the DFU mode which allows me to program it. NOT

Posted on April 08, 2018 at 09:13L496 port G includes two I2C- PG13/14 I2C1 and PG7/8 I2C3. But the two I2C cannot output and the oscilloscope does not display waveform.I2C1/I2C3 can work correctly if they are mapped to other ports. So I think the I2C1/I2C3 modules are ok in L496.On the other hand, if I set PG13/14 and PG7/8 pin mode as GPIO output, they can work well. So the GPIOG module is ok.So what is the problem with GPIOG I2C? I know Port G[15:2] are independent from other ports. But I connect Vddio2 to Vdd in the test. Please see the code below.Init Code: LL_AHB2_GRP1_EnableClock(LL_AHB2_GRP1_PERIPH_GPIOG); HAL_PWREx_EnableVddIO2();LL_GPIO_SetPinMode(GPIOG, LL_GPIO_PIN_13, LL_GPIO_MODE_ALTERNATE); LL_GPIO_SetAFPin_0_7(GPIOG, LL_GPIO_PIN_13, LL_GPIO_AF_4); LL_GPIO_SetPinSpeed(GPIOG, LL_GPIO_PIN_13, LL_GPIO_SPEED_FREQ_HIGH); LL_GPIO_SetPinOutputType(GPIOG, LL_GPIO_PIN_13, LL_GPIO_OUTPUT_OPENDRAIN); LL_GPIO_SetPinPull(GPIOG, LL_GPIO_PIN_13, LL_GPIO_PULL_UP); LL_GPIO_SetPinMode(GPI

Posted on June 05, 2018 at 17:23ST seems to do reading all files in a directory in a hard way.I am combining two examples about Sdfat but ST uses unfamiliar commands for reading all files in a directory. I think I could do it with a hard way but isn't f_findfirst/f_findnext more common.I have examples for reading all bmp files and an other showing one jpg file.Edit: By the way. I still have to accept cookies several times in one session.

Posted on June 05, 2018 at 17:09Hi,I have been doing a little work recently with the STM8S003k3 Discovery board, where I attempting to create a 800Hz signal with a 80/20 duty cycle. The issue I am experiencing is that I have no output on the pin!Now I'm almost certain that loading values etc are correct and this is instead a order of operations issue, with that being said, what is the correct procedure for register configuration etc? At the moment I am working as follows:1. Set HSI and enable clock to timer 22. Initialise GPIO for input floating no interrupt PB6 & PB7.3. Initialise GPIO for output push-pull fast mode PD2 (Timer 2 CH3).4. Set prescaler and set ARR (*MSB first), (**PSCR LSB first).5. Set CCR3 with value to obtain 80% duty cycle.6. Set CCER2->CC3P = 0, active high.7. Set CCMR3->OCM = 6, PWM 1 mode.8. Set CCER2->CC3E = 1, enable CAPCOM3 output.9. Set CR1-> CEN = 1, run the timer.I understand that there is constraints regarding the order in which

Posted on June 05, 2018 at 11:54Hello there,I found some differences between the memory mapping of the Datasheet and the Reference Manual:DS STM32F4x Rev10 - Memory map pg. 86Option Bytes 0x1FFE C000 - 0x1FFE C008Reserved      0x1FFE C00F - 0x1FFE FFFF/* missing info C008 - C00F -*/RM STM32F4 Rev16  - Table 6. pg. 77Option Bytes 0x1FFE C000 - 0x1FFE C00FSame for bank to on 0x1FFF C000 ...This defines no problem but which should be referred to?

Posted on April 10, 2018 at 13:14Hello,i've followed many tutorial to try to get UART with interrupt working on my stm32l476rg (nucleo board) :at the main.c, before while(1) loop :HAL_UART_Transmit_IT(&huart4, (uint8_t *)welcome_str,sizeof(welcome_str));this doesn't work, but in polling mode, it's working :HAL_UART_Transmit(&huart4, (uint8_t *)welcome_str,sizeof(welcome_str),100);i'm using hc-06 bluetooth dongle, and receiving it on android Phone, it should be able to receive interrupt without any problem...?what i'm missing here ? any triggering stuff or ..?thank you#uart-it #stm32l4+

Posted on January 19, 2018 at 04:27My Samsung mobile upgraded from Android 6.0 to 7.0. But after that the 24SR seems can't detect from mobile NFC. It happens only after the 24SR IC locked in read/write. For unlocked the chip by 24SR discovery board hardware, 24SR can detect by mobile again. I tested in Android 4.4,5.0 and 6.0 and all work. So is there any changes in Android 7.0 that cause this problem ? Please advise and thanks.

Posted on May 31, 2018 at 16:58Hi everyone,I have a STM32F7 Discovery board and I would like to upload new firmware on it.I read AN2606 and AN4826, and I saw that it's possible to split the flash into two memory banks (nDBank = 0) and I can start either on one or the other bank using BOOT_ADD0.I have downloaded the extended_cube_dbank_f7 file that provide an example of dual bank boot. I followed every steps, which isn't hard, but I am still not able to boot on the second bank whether I change BOOT_ADD0.I have used STM32 Utility to configure my MCU (unchecked nDBank in Option Bytes, while nDBoot is still checked), I have programmed the two banks with different firmware @0x08000000 and @0x08100000. The BOOT_ADD0 parameter, under Boot adress option bytes section, has no effect whether I use 0x0080 or 0x0081. I can boot @0x08000000 but it seems like something goes wrong when I try to start @0x08100000!I followed the tutorial step by step, did I miss something?&nbs

Posted on June 04, 2018 at 10:30Hi.I'm using keil for programming a stm32 board. In the start up file .s there is a call to __main after the call to SystemInit. Where is the definition of __main? What's the difference between main and __main?
