Hello dear All,On STM32G0B1 I'm trying to capture PORTD[0-7] value with DMA on EXTI0 event (PD0 falling edge)(Read PORTD value in EXTI0 interrupt is too slow for this application -> PORTD change value before entering IRQHandler())I configure EXTI and...
in stdlib version1.9.0, void I2S_Init(SPI_TypeDef* SPIx, I2S_InitTypeDef* I2S_InitStruct) { uint16_t tmpreg = 0, i2sdiv = 2, i2sodd = 0, packetlength = 1; uint32_t tmp = 0, i2sclk = 0; #ifndef I2S_EXTERNAL_CLOCK_VAL uint32_t pllm = 0, plln = 0,...
Hi there,I am using cubeMx to config the LwIP project which is based on STM32F429BI;I connect the MCU to the route and ping the MCU by PC successfully in DHCP or static IP mode.I can normally get the MCU IPv4 address in static IP mode but fail in DHC...
Hi Can anybody guide me to choose right STM chip for camera interface and parallel display interface, Thanks
Hello everyone,I'm currently in search of an Analog-to-Digital Converter (ADC) for a project I'm working on and would greatly appreciate your recommendations. Here are the specific requirements:Sampling Rate: Between 10 Samples Per Second (SPS) and 3...
I started getting this message when I try to debug my code. However, there are currently no breakpoints in my code at all. I have gotten this in the past and I deleted and redownloaded the IDE which I really do not want to do again. I am running i...
Hello! I dont know where to find received data after HAL_I3C_Ctrl_Receive_IT progress. I set I3C of my H563 as master and sent ENTDAA and master read , the slave answered both command. The interrupt of slave reflects that master re...
Hello,I have configured a DMA channel to perform a memory-to-memory transfer triggered by EXTI. I would like to automatically re-arm channel at the end of every completed transfer so that it is ready to process the next EXTI trigger event without any...
I'm trying to see what's possible in terms of a bootloader in a custom application of an stm32f722. We have an external 2-megabyte flash chip on the QSPI bus, along with the internal 512-kilobyte flash. I'd like to make the bootloader stored on inte...
HelloWhen adding the internal temperature sensor reading in the STM32H750 micro FW, out of curiosity I collected voltage reading data based on different sampling times.Based on our ADC clock speed (37.5 MHz) and the datasheet requirements for the tem...
