Scenario:one STM32F0, as part of a bigger system, has the purpose of monitoring and controlling the power rails.To be able to update the firmware in the field, a U(s)ART connects it to the Linux ARM SoC also in the systemthe latter is supposed to pro...
Hi,I have used STM32l562-edk evk hardware and stm32cubeide for software. I have enable freertos in the project. For debug print message purpose I have created one function named as logPrint. char g_msg_buf[100];void logPrint(const char *format, ...){...
Hello, I am working on a project in which I have to write data from my adc into a µSD card using SDMMC1 peripheral.In my testing program to see the ADC1 behaviour with the DMA all work. My buffer stores the datas from my ADC using DMA and the callaba...
Hi all, how are you?. Yesterday I was unable to make the RTC work on my STM32F103C6, miraculously I've noted that the program was giving an error condition (until that moment I wasn't using the error handler function, now I'm using it) then I found t...
Hi all, how are you?. I had that what I think is bug after enable the seconds interrupt by using the macro __HAL_RTC_ALARM_ENABLE_IT(&hrtc,RTC_IT_SEC);in my main() function, then I had to put the function CLEAR_BIT(RTC->CRL,RTC_CRL_CNF);after the ...
Hi everybody,I've been trying for a while to read multiple bytes from an LIS3MDL accelerometer. I know how to read and write registers but one at a time. I can't figure it out the multiple part... So, if I want to read from reg 0x27 to 0x2D, I unders...
Posted on May 31, 2017 at 19:33I am using an stm32f030x8. I am using the HAL. Normal operation I can use I2C reads/writes with no problems; however, I can occasionally have errors in the receive data when more activity is taking place on the MCU. I ...
I am sending a 140kB array from the stm32f746 DISCO board. I am using the core cycle counter to measure the speed. The SYSCLK is set to 50Mhz, 20ns per cycle. It takes 709 core cycles to complete the transfer. I calculate the transfer speed to be 70k...
