I am currently working on a STM32 project which I generated for System Workbench for STM32 via CubeMX, and now I want to switch over to Atollic TrueStudio. Can somebody please tell me what changes should I make to my current dev env to work in Atollic Truestudio?

Hi,I have configured my Nucleo-64 board with the STM32F030R8 with the STMCube software.The HSI is set as system clock (no PLL) and measured over the MCO pin (PA8). I will attach the main.c.The measurement you can see below.There are breaks within the clock signal so the controller stops running.Do you have some ideas what's the cause?Thank you!

What's the easiest way to obtain a list of all STM32F446 hardware registers? Extracting them from different H-files or from the reference guide in pdf-format seems like a lot of work. Is there a more efficient way?

I am trying to convert a signal from accelerometer to a digital value. The output coming from accelerometer is in mv so I have added a non inverting voltage amplifier, then too I am getting a dc voltage at the output of opamp so I have added two capacitors to eliminate dc voltage in my signal. Here are my issues, When I tried have connected a potentiometer and tried, I didnt find any issues, ADC is working perfectly but when I am trying to connect the output from the capacitor to PA1 and ground, I could not able to get the reading from controller!!!! I mean the voltage across capacitor is dropping to mV . I have measured the voltage across capacitor in oscilliscope by not connecting to PA1 its working perfectly, peak to peak is coming at 4V when vibrating.. but the moment I connect the ouput from capacitor to PA1 and measure the voltage across PA1 to GND. its dropping to mV in which i cannot do the data acquisition.  Are there any hardware connections/ biasing I need to do for acq

I am working with the STM32F4 family. External interrupts have a register called EXTI->SWIER that makes it possible to generate external interrupt from software. Do the timers have something similar, a register that I can use to generate timer interrupts in software?

STM32CubeMX V4.27.0 release note states that STM32H7 uses firmware V1.4.0. Whereas in reality it uses V1.3.0. Is it possible to download STM32H7 firmware V1.4.0. I could not find it anywhere. Is firmware update planed?

Posted on April 07, 2018 at 08:49Hello,I'm having trouble setting up the SAI peripheral clock on an STM32L476RET6 using Stm32CubeMX (Version 4.25.0).I want to use the SAI2A as Master Receive on a MEMS MIC ICS43434 with I2S with FS = 48KHz. and SCK = 3.072MHz.FS = MCLK / 256So I put 12.288 in the field ''To SAI2 MHz'' and press enter but CubeMX suggests 12.235...12.235 / 256 = 47.79KHz would be a bit out of the way I want. So I put 12.288 * 2 = 24.576 and CubeMX suggests 24,571 which would theoretically give me a FS of 47.99 ... KHz which I think is good but when compiling on Keil (V5.24.2.0) and measure with my oscilloscope:FS = 58.7KHz insted 47.99 KHzSCK = 3.74MHz insted 3.07MHzMCLK = 15Mhz insted 12.285MHzthe microphone responds okay but obviously with an incorrect sampling rate for my application.I also configured another pin so that I could measure the clock generated by the HSI and measure 16Mhz as well as expected.on my board I have a crystal of 16MHz but when using it I have t

I have recently faced with problem that the real timeout and calculated aren't equal. The formula is described as in the screenshot below. But the WWDG initiates a reset when the counter (T[5:0]) changes value from 0x40 to 0x3F. Then we have only 128 - 64 (0x40) counts until a reset occurred. Shouldn't the formula be like t_wwdg = t_pclk * 4096 * 2 ^ (WDGTB[2:0]) * (T[5:0] + 1 - 0x40) ?

In my project, PA15 pin is configured as o/p pin and is responsible to control BG96 module connected with the MCU.When I load program in controller and open debugging session, SDO shows 1V signal on PA15 (i.e. when controller is RESET).When PA15 is SET, its voltage level is 3.2V and when it is RESET, its voltage level is 0V.Can anyone guide me how to set PA15's voltage to 0V when MCU is RESET ?This situation is mandatory in my project at it can misguide my BG96 module.Thank You,Maunik Patel

I am working on a hard fault handler were I want to store some key values into ram before resetting. This data will then be further handled at next boot up.My problem is that the data does not get written into RAM unless I step through the writing code with a debugger. I am using the NVIC_SystemReset for resetting which comes with the STM sdk and looks like below.** \brief System Reset \details Initiates a system reset request to reset the MCU. */ __STATIC_INLINE void NVIC_SystemReset(void) { __DSB(); /* Ensure all outstanding memory accesses included buffered write are completed before reset */ SCB->AIRCR = ((0x5FAUL << SCB_AIRCR_VECTKEY_Pos) | SCB_AIRCR_SYSRESETREQ_Msk); __DSB(); /* Ensure completion of memory access */   for(;;) /* wait until reset */ { __NOP(); } }According to the documentation the __DSB() macro should take care of ensuring that any pending memory writes are completed.Since the data gets written when stepping through with the debugger I am

Posted on February 21, 2017 at 04:11Hi Everyone,I was looking for a tool that was able to bootload an STM32F767 microcontroller via USART which I thought I found when I came across the STM Flash Loader Demonstrator (version 2.8.0). However, there was no '.STMap' memory map file for this processor family, the closest was STM32F74X/5X.  I created a new memory map file for the STM32F767 (see attached) which allowed me to successfully connect to my micro using the Flash Loader Demonstrator. However, I cannot perform an erase, program or download. The error message that I receive says 'Fail. Check read/write protections'. However, when checking the flash readout and write protections they are disabled. Has anyone had success getting this flash loader tool to work for STM32F76X parts?Also, does anyone know the meaning and significance of 'BID' in an '.STMap' file? I am currently using 'BID' for STM32F74X/5X parts - maybe this could be the source of the problem?

Hi, I interface Controller with ST25DV04K and able read and write registers , when i am working on I2C protection on Area1 to 4, In both I2C security session close and open mode i was able to read and right even though i set the Area 1 to Area 4 permission in I2SS register , Could you pls let me know any additional things need to handle ?

the time clock (RTC) on this device (STEVAL-SMARTAG1) seem to be off after half day of running, is there a fix available ?

Hello, I have a problem to communicate with 24LC02B memory. If I look with the logic analyzer, no data on CLK and DATA pins. Here is my code. What is wrong?Thank you#define I2C1_DEVICE_ADDRESS 0x50 #define MEMORY_ADDRESS 0x08 uint8_t xBuffer[1];   __HAL_RCC_GPIOB_CLK_ENABLE(); __HAL_RCC_AFIO_CLK_ENABLE();   GPIO_InitStruct.Mode = GPIO_MODE_AF_OD; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; GPIO_InitStruct.Pull = GPIO_PULLUP; GPIO_InitStruct.Pin = I2C_SDA_Pin; HAL_GPIO_Init(I2C_SDA_Port, &GPIO_InitStruct); GPIO_InitStruct.Mode = GPIO_MODE_AF_OD; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; GPIO_InitStruct.Pull = GPIO_PULLUP; GPIO_InitStruct.Pin = I2C_SCL_Pin; HAL_GPIO_Init(I2C_SCL_Port, &GPIO_InitStruct);     I2C_EEPROM.Instance = I2C1; I2C_EEPROM.Init.ClockSpeed = 100000; I2C_EEPROM.Init.DutyCycle = I2C_DUTYCYCLE_2; I2C_EEPROM.Init.OwnAddress1 = 0x00; I2C_EEPROM.Init.OwnAddress2 = 0x00; I2C_EEPROM.Init.AddressingMode = I2C_AD

I attached a battery to my STM32, and my RTC is now keeping the time when the board is not powered.But when not powered, the clock is also not advancing, which means that when I power on the board, the RTC shoes the time when I powered off the board.What else do I need to set here so that time remains accurate?

I've an STM32F103C8T6 CPU, but I can't find appropriate linker file. The closes file is `STM32F101XB_FLASH.ld`. Can I use it with change following line (#43):FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 128KtoFLASH (rx) : ORIGIN = 0x08000000, LENGTH = 64Kor there are other differences?

Hi,I'm trying to write some code using STM32CubeMX And HAL H7_V1.3.0.I was trying to use the Receiver Timeout feature of USART6, but there are a few places where it was missing:CubeMX did not allow me to configure this option, but this was easy enough to change in the user codeWhen I wanted to use the interrupt associated with this feature, I found that there is not way to define it with the __HAL_UART_ENABLE_IT function. There is a list of available interrupts, and the Receiver Timeout Interrupt is not one of them.Does anybody know if this feature will be supported in future versions of CubeMX and HAL?Is there a way to bypass this?Thanks in advance,Yan

Posted on February 16, 2018 at 20:28Hi,I'm trying to run an example program - BLE_Sensor DEMO - built from sources.I am using TrueSTUDIO for STM32 (v.9.0.0). The sources are from BlueNRG-1.2_DK_2.6.0 kit.Unfortunatelly, when I download the image, the board does nothing: no led blinking, no BLE communication.However, when I download prebuilt image (from Firmware folder in the development kit) it works fine.What I am doing wrong?Kind regards,Piotr

I am interested in using one of the Nucleo boards, either F401RE or F429ZI (these two are both supported by Zerynth ide) but I need 15 adc channels. The 401 has 1 adc with 16 channels, the 429 had 3 adcs and 24 channels. But in all the documentation it appears that not all the adcs are available. On both boards they seem to stop at 6, which is what the Arduino Uno offers. Both boards have a lot of other (non Uno) pins available but I have not been able to find in any of the documentation what the pins are for. I wold hope that 10 of them (on the 401) would be the other 10 adcs. Can anyone please point me in the direction of some documentation that shows the whole pin map for these boards?Thanks,Ian

Hello,I have a board on my desk where the RES pin (#5) of LIS2HH12 is not connected.The data sheet says, Connect to GND. OK ... not good ...As I do not get any response of the accelerometer via I2C, I would like to know if this pin is the reason. I can't easily connect it due to the package ...Does RES stand for RESET or does anyone from ST can confirm that connecting RES not to ground results in having no I2C access?Thanks.

When i looked into the doc , i found that "To be usable on any MCU, this driver calls several IOBus functions.  The IOBus functions are implemented outside this driver, and are in charge of accessing the MCU peripherals used for the  communication with the tag",  could you pls share if any document steps available to port driver on different micro ?

Hello, I have some problems with my STM32F446RE (Nucleo-64 )and terminal program (as puTTY and so on).I connected it by its usb connector (CN1) and it was recognized as Virtual Port: Well!So I opened STM32Cube MX and set:-STM32F446 board.-USB_OTG_FS, as Device only (no VBus or SOF).-USB_Device as CDC (Communication Device Class)RCC clock is HSC with Crystal/Ceramic Resonator , 8Mhz Input Frequency, 168Mhz HCLK and 48Mhz to USB.I have generate code for Keil (and for Atollic too, with the same effect).So I modified main.c by-Inserting: #include "usbd_cdc_if.h"The "int main(void)" function now is:int main(void) { /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* Configure the system clock */ SystemClock_Config(); /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_USB_DEVICE_Init(); uint8_t Text[] = "Hello\r\n"; HAL_Delay(1000); while (1) { CDC_Transmit_FS(Text,6); HAL_Delay(1000); } }in "usbd_cdc_if.c" I set:#define APP_R
