Hi,I'm developing a new project that will use a GSM module. On the PC, this presents as three (3) Endpoints e.g. COM5, COM6 & COM7. I need to communicate with the GSM module on at least two of the three endpoints using the AT command protocol.Will a ...
I traced the code flow and I found that the SPI flash should be formatted.I used an SD-Card and traced the code while it is mounted and knew that it searches in sector 0 for the record signature and the pointer to the partition sector. Then it reads ...
Hi everyone,I want to start using the H743ZI serial communication with an hyperterminal software but i am not able to compile my project. I am using the STM32Cube_FW_H7_V1.3.0 UART POLLING example as a reference but everytime i try to compile my proj...
Hello,I don't really have a problem, but I'm asking myself questions and I didn't succeed in synthesizing them and find answers on Google.Problem 1:Several tasks want to use the same peripheral, lets say SPI bus for example. What is the best way to p...
My work environment as below :1. Window 10 (Version 10.0.18362 Build 18362)2. Laptop processor: AMD PRO A12-8830B R73. My Discovery Board: STM32F407VG MCU 4. Driver Installed : en.stsw-link009 and Virtual Com port : VCP_V1.5.0_Setup_W8_x645. Codin...
I am wondering whether STM system bootloader enables internal UART pull ups? I guess it doesn't, but I can't find this in ST docs.My board does not have external pull ups on UART line and I want to avoid having RX pin floating.
Hi all!I intend to use USB and CAN on an STM32F072. The datasheet describes a 1KB SRAM buffer, 768B for USB and 256B for CAN.In CubeMX, when I set up the USB as a VCP, by default it sets 1000 bytes for "USB CDC Tx Buffer Size" and 1000 bytes for "USB...
Hi,we have a hex file coming from GCC which we cannot flash onto the MCU with our own flashing tool (F412 and L471 tested).While investigating, we found that after a shorter line all writing seems to fail silently (still receiving ACK).In the picture...
Hi,I'm new to using HAL, and I'm having several issues with setting up the SPI.I'm using SPI 1 on an STM32F429ZGT6, and using KEIL as my IDE.I've just tried initializing SPI 1 by configuring GPIOA Pins 5, 6 and 7 for their SPI Alternate functions.I s...
