I am trying to communicate with a PIC microcontroller using the I2C interface using a STM32F103. I have a recurring problem: everything is fine until I run this function:static HAL_StatusTypeDef I2C_WaitOnMasterAddressFlagUntilTimeout(I2C_HandleTypeD...
I'm using MX25V1635F on WB55Below, read/write functions work fine#define SECTOR_ERASE_CMD 0x20#define QUAD_IN_FAST_PROG_CMD 0x38But in memory mapping mode, only few bytes correctly or even nothing right,CS, SCLK work as expected but D0 seems like out...
Hello,I was trying to use USART1 in a project with STM32H742VIT6 but decided to use LPUART1 instead. I found that using the same BRR computation the baud rate is coming out MUCH slower (it's around a factor of 51 slower). LPUART1SEL is in the reset...
Hi,I would like to inquire whether it is possible to perform internal I2C and SPI loopback tests on the STM32F767ZI board.Regards,Mounika
How in the world of programming is this possible? I got enough other problems to fix already.It worked flawless before! ld.exe: G431RBT6_Bootloader.elf section `.text' will not fit in region `FLASH'ld.exe: section .applicationBlock LMA [000000000801f...
Hello,I am working in a new project (a USBC rechargable battery LORA board with temperature module) with some leds and a button. I attached the schematic here.I only program all my boards with the USART mode.I choose the L4 family because I want to s...
Hello all, I'm learning about Nucleo F746ZGT6 . and also I'm doing some projects related to this board. I want to ask how much digital voltage & Current at the one pin of Nucleo F746zgt6.
Hello everyone,I am working on a signal analyser device, which needs to transmit data serially as fast as possible (idealy 1Mbaud/s).I am doing the following loop to transmit: uint8_t buf_high[1] = {124}; // '|' uint8_t buf_low[1] = {48}; // '0' ini...
Hi, i came across a program to config alternation function for SPI GPIO port A. GPIOA->CRL |= (11U<<20); // PA5 SCK AF output push pull GPIOA->CRL |= (11U<<28); // PA7 MOSI AF output push pull What does the 11U means? i know its somethin...
I have a project , used regular conversion ADC1 Vrefint Channel and Temperature Channel, and used injected conversion ADC2 extern Channel(ext.CH1 and CH2).ADC2 CH2 connect 2000mV voltage , CH1 is changed. If CH1 over 3.6V,the CH2 conversion is error...
