I'm using STM32F411RCT chip and using I2C3 slave is BMP280 * 2ea and HDC1080The bmp280 is implemented as a function of HAL_I2C_Mem_Read.HDC1080 is implemented as a function of HAL_I2C_Master_Transmit & HAL_I2C_Master_Receivenow, I change this fun...
During development I've been using ST-LInk to program the STM32L433 which of course works perfectly. I want to release the firmware and allow users to be able to update the code over UART2. I've set BOOT0 and can see the device using the latest versi...
Posted on July 17, 2014 at 18:45I have two discovery cards setup for bi-directional SPI. On the slave, I'm using SPI3 with DMA1 support (TX stream = CH0_S5, RX=CH0_S0). I have the TX stream flow control configured as DMA_FlowCtrl_Peripheral (tried b...
I have a 32F746GDISCOVERY and would like to test the dsp functionalities with a correlation.I have the following code:#include "arm_math.h" extern void arm_correlate_fast_q31(q31_t * pSrcA, uint32_t srcALen, q31_t * pSrcB, uint32_t srcBLen, q31_t * p...
Hi everyone,I am trying to get USART3 running on my STM32F429I-DISCO board. USART3 is configured with the following configurations:Mode: AsynchronousHardware Flow Control: DisableBaudrate: 115200, Word Length: 8, Stop Bits: 1GPIO: PD8 = TX, PD9 = RXI...
Posted on January 10, 2018 at 21:56Hello, I've just built the UART sample code for the 722ze Nucleo board and have a problem. I have not modified the code (except for the transmitted character buffer). The sample code shows setting up the unit for ...
A reference to an existing explanation would be fine.I can't find a reference manual
Hi everyone, I was just wondering if there was any STM32 MCU in a flip chip packaging configuration ? I have seen some BGA packages but I came to understand that it didn't mean that the chip was flipped inside...Any info on the matter would be appre...
Hi everyone,I'm slightly confused here.I'm putting my micro into stop mode, but I can't seem to wake it up using an interrupt.Here's how I'm setting it:__HAL_RCC_GPIOA_CLK_ENABLE(); GPIO_InitTypeDef GPIO_InitStruct; GPIO_InitStruct.Pin = GPIO_PIN_4...
Hi there. I'm having a lot of trouble.I've managed to get UART (just direct calls, not interrupt based), PWM, and ADC working on a Nucleo board (namely, the STM32F070RB board). However, I'm having serious trouble getting a simple push-button to fire ...
