We would use a STM32H743II with an external ldo for vcore. In the datasheet are tables (page 114, table 31) with regulator on but no tables with regulator off.In the datasheet at page 114 is a table (table 31) for maximum current vs. junction tempera...
I need to implement an ADC to measure phase voltages, so I want to set the N phase as Vref- and get the values of other 3 phases (comparing with N phase) on the output of the ADC. I am using single-ended mode.Is it possible to do this? How can I do i...
Here is the code that doesn't work. Any suggestions?UART_HandleTypeDef UartHandle;uint8_t MyRxBuf[ 10 ], MyTxBuf[3];int main( void ) { uint32_t t_print; int16_t i; HAL_Init(); SystemClock_Config(); /* Put the USART peripheral in the Asynchronou...
Hi, I am looking for board which support 32bit data size in SPI Mode. I found NUCLEO-H743ZI2(https://www.st.com/en/evaluation-tools/nucleo-h743zi.html) development board but not very clear that it will support 32bit data size in SPI Mode or not. As...
I want to use STM32G474 controling a boost converter.A ADC channel(configered as injected convert) sense the inductor current，I do the configuration like this:The ADC channel is triggered by at middle of MOSFET on time;The ADC sensed pin is routed...
Hello everyone,We are using the STM32F103C8 connected with the Microchip RN4871 BLE module over UART1. We would like to update the firmware of the STM32 CPU over BLE but we are encountering a few issues. Our BLE module, although it works great for ou...
I want to use the external clock mode 2 but it dose not work ,configure the PA12 that connect to TIM1-ETR AND make push button pull down to send pulses to that pin(PA12) to detect high edge and make up count to the variable "upCount" in the code ,i t...
I am trying to read capacitance and temperature from the AD7746 capacitance-to-digital converter, using STM32F103 and HAL I2C library (SDA and SCL pulled up with 2k and Vcc = 3.3 V). I did it before using AVR (using Codevision) and it worked fine, bu...
When i used a bootloader to make user program run from QSPI Nor Flash in MemoryMappedMode, it worked well.But now i want to run user program from FMC SDRAM.So firstly i plan to initialized both QSPI Nor Flash(MemoryMappedMode) and FMC SDRAM,then copy...
