I inherited someone else's code who knows more about the STM32L1 architecture than I. In some code paths, the HSI can get changed to 8Mhz from the HSE of 32Mhz, and sometimes it can't.It fails because of this loop timing out.do { HSIStatus = RCC->C...
I have been trying to make the Arduino talk to the STM32 via I2C but i just cant get it to work. The STM has to be in a form of a slave mode but i can't seem to figure it out. So if there is anyone who could help me or give me a form of an example fr...
Hello,I have an issue with my DAC. I am using a Nucleo STM32L476RG and my project consist of acquiring data from a mems microphone over i2S using the SAI and then send it to the DAC in order to view it with an oscilloscope. First I initialize the DAC...
Hello, i have some questions about current injection onSTM32G431CBT3 pins.On datasheet Table 15 it is reported:IINJ(PIN) -> Injected current on FT_***, TT_xx, NRST pins ->-5/0NOTE3:Positive injection (when VIN > VDD) is not possible on these I/Os and...
Dear community, I am facing a weird problem on using the SPI after migrating my codes from STM32F407 to STM32F767.The SPI is configured as slave and interfaces with another STM32F406 MCU as master. The data received by the slave is sometimes shifted ...
Hello, everytime when I try to debug my program it stucks after the HAL_Init() in the main, so it never actually reaches the code provided by me. As I stepped through the code, I noticed that it gets into a infinite loop where it always calls a funct...
STM32H723VET6: I cannot find the demo board in website? Does it have the demo board？I need a reference schematic. Can you send it to me?
The fourth parameter in the HAL_UART_Transmit function.Suppose I send 5 characters, is probably 5*9==45 .Transfer rate 115200 Bits/sWhat delay should I set in the HAL_UART_Transmit function?5 characters at a speed of 115200 Bits/s will be transmitted...
