On an STM32F429ZI, I'm using USART3_RX to receive information via DMA into a circular buffer. The buffer is 4096 bytes long.If I send 1 or 2 bytes at a time (i.e. with a delay of ~100ms+ between transfers), things work correctly. By "work correctly" ...
Hello,I am trying to synchronize two PWM outputs on an STM32H7: TIM4 channel 2 and TIM8 channel 3N.To do this I am using the HAL synchronization functions, setting TIM4 up as master with "HAL_TIMEx_MasterConfigSynchronization" and TIM8 with "HAL_TIM_...
Hi everyone ! I read in the datasheet that I need the VREFINT_CAL to calculate my real VDDA but I don't find it in the datasheet. In every other model's datasheet you can find the VREFINT_CAL easily but not in the STM32L0 one. Is someone kno...
I'm trying to use both internal op-amps to sample analog inputs with ADC1 and ADC2. When the op-amps are setup using CubeMX (latest version), 3.3v stays present on PA6 input. PA0 works as expected. Both ADCs sample correctly but the waveform input th...
Hello,we want to build a system with STM32H7, hopefully one of the new up to 480 MHz devices. And we really need a high clock of 400 MHz and above. On the other hand we need low power and we use ADC and DAC, both requiring a 3.3V Vref.Now my question...
I am sensing the voltage using stm32f103c8 module.using Keil micro--vision 5register level codingcode:#include "stm32f10x.h" float av,volt; int main(void) { // SEND A CLOCK SOURCE FOR ADC //LcdSend2StringWithDelay(50000,"Start Clock",""); ...
Hi there,I'm working with an STM32L073RZ CPU and Mbed OS 5.12.0 and experiencing an issue that I'm not quite sure how to describe. The processor gets into a state whereby it oscillates a pin (PA_5 which is setup as an InterruptIn that pulls down) and...
Using an STM32H753, I have boot code in bank 1, sector 0 (0x08000000) that detects and jumps to application code in bank 2, sector 0 (0x08100000). In the application code I am trying to erase and rewrite bank 1 sector 0, but the MCU locks up (with no...
Dear All,i configured an input pin as external interrupt with rising edge detection and pulled it down internally.i apply a pulse train which it sets and resets within the time that the interrupt is disabled.i expect that the ISR executes when it is ...
