The STM32 IDE project shows some "default" mapping to use in the U[S]ART1-6. For example, UART1 has PA9(TX) and PA10(RX). Are these GPIO pins fixed? Can any be used? Is there any restriction on which pin can be used with which UART block?In particula...
Hi,In my program (running on STM32F446RE, with 512 KB flash and 128 KB SRAM) I defined two big arrays:int main(void){ /* USER CODE BEGIN 1 */ int16_t data_in[64000]; int16_t audio_buffer[16000];The code can run normally when the data_in array is not ...
Hi,I am using stm32f030 to read adc value(truestudio). ADC reads value on an interval of 10 minutes. It is observer that ADC reads value for first 5-6 times,and after that it reads 0v.The readings we get is also different from what is measured on adc...
Is it possible to store a variable and read it after deep sleep or sleep?
Dear All, I've seen from ST website that STM32H7 is compatible with a QSPI PSRAM of the producer AP Memory. IoT PSRAM (QSPI PSRAM) - AP Memory IoT RAM solution is the ideal solution, specifically when the application memory needs exceed the SRAM embe...
The DS3231 MC has two open drain pins, SQW and SQW32, which can generate, respectively, 8Mhz and 32768 signals. Can I use these to start stm32s, sort of like an external generator? If so - those pins are open drain, what kind of pull-up resistors do ...
Hello,In some weird way, the ADC is affecting a certain pin (PA7) even though I did set that pin as one of the channels to be sampled. I trigger the ADC every 100ms, single conversion multichannel (only 4 channels) with DMA. When ADC is triggering e...
I wanted to toggle an LED in STM32 , there's this GPIOx_BSRR ,The boundry address for the GPIOC is 0x4001 1000 and the register (GPIOx_BSRR) is on the offset 0x10,I wanted to toggle the led_13 using bitbanding but Im not getting to the alias address0...
i am trying out the example code which is given in Repository from STM
I am using ADC_Regular_ConversionMode with Range 2. The first rank is channel1, the second rank is channel2. I would like now to adapt code, because before I have only 1 range and only 1 channel.I am calculating average "average += buffer[i];" in the...
