my problem is that the DMA only writes to the first address of the buffer, means that when i look on the buffer, the last byte of the message is stored in the first place of the array, and the rest of the data is overwritten.what could be the problem...
eternal interrupt routine works with some delay if i remove delay then it not work what is the reason how can i solve this?*code work with some for loop delay.void EXTI3_IRQHandler(void) { /* USER CODE BEGIN EXTI3_IRQn 0 */ for (int z = 0; z < 50...
CubeMX ver 5.4 F1 package ver 1.8.0 and CubeMX ver 5.5 F1 package ver 1.8.0 when using CAN pins PA11 and PA12 the receive interrupt does not work. If you make pins PB8 and PB9 everything works. It also works on any pins if you configure loopback mode...
PN532 NFC/RFID module with STM32F429Zi communication via HSU
Good morning,i' m working with stm32g4 and formy application i need use internal opamp in non- inverting configuration withexternal resistor how show the figure below (figure form AN5306). I don’t understand if is possible connect the output of opamp...
I am using STM32F103VBTx. I have configured ADC using DMA method. We are getting some noise on PCB due to which ADC values are not captured properly. We see a lot of variations even after Calibrating ADC values through software. We are trying to eli...
Hi all,I have some problem with LCD1602 + pcf8574 (I2C) and STM32F107pcf8574 operate as SLAVE.I setup i2c in CubeMX and used this tutorial ( https://controllerstech.com/i2c-lcd-in-stm32/ ) to operate LCD, but I failed, then I write a I2C bus scanner ...
I have a simple and trivial question.I read the registers of TIM3 in encoder mode in polling and so far everything is ok. The encoder is a normal panel encoder with knob.I want my reading of the encoder register not to fall below a limit (this exampl...
Hi, Can someone help me find the minimum voltage Vcc of stm32f103c8.Lowest voltage that will allow for maximum clocks frequency. And wont interfere with usb (pullups at data line to vcc).And adc.2.4 V is minimum when using adc. But will it run at ...
Dear ST community,we are planning using stm32f0 as driver for our X-Y control Unit. with please see the attachment.The requirement is to update the application of stm32f0 via SPI.And we would like also to use the parts of the HAL library.Is those two...
