Hi, I am struggling to get SPI and I2C to work at the same time on my project I have tried multiple things (DMA, interrupts etc...) are there any example projects that already have this implemented? I am simply trying to read an I2C sensor value and ...
Hi,In my project, I communicate with STM slave I2C. I can receive data via I2C but I cannot send data. As you can see in the photo below, the packetData is filling up, but when you send it, it only sends 0x00. what is the problem? what can I do?
Hello everyone, I'm exploring the feasibility of transitioning from 2x Teensy 4.0 boards to an STM32H755XI for a sensor-intensive application. The project involves interfacing with 16 VL53L4CX sensors and managing their data acquisition and processi...
The CAN communication between the main control board (SMT32F407VGT6) and the same server board (STM32F407VGT6) shows that the ambient temperature is below -10 degrees, the communication is abnormal, and the ambient temperature is above -10 degrees! I...
I'm working on implementing USB Host support for the STM32F407 without using the STM32 HAL. I've followed the datasheet and gotten as far as sending a GetDescriptor packet (though I haven't confirmed that on the logic analyzer yet), but I don't know ...
hi i am having some difficoulty's where i cant find a solve for: problem 1 ADC1_channel12 feeds me a value back around 4030 while its voltage on the pin is 0.0Vproblem 2 ADC2_channel3 is always reading 0 i configured all ADC channels to place data in...
Dear SIR,What is the max number of external inputs using interrupt at the same time?In my application, it uses 22 GPIO as external input as Fig.1.1. I use STM32CubeMx to set "PB1" to "GPIO_EXT1" then set "PC1" to "GPIO_EXT1", after setting "PC1", the...
Any Core Hardware Register available to user which is not used by HAL or the Processor itself which I can safely use without disturbing the rest of the MCU?I am using an STM32L431. To keep the System State in check I am using a Volatile uint32_t vari...
One of the practices of software design is to use volatile buffers when ISR and main loop access the data in the same buffers. This makes sure certain compiler register optimisations do not create unreliable code.If I look at the HAL code for the USA...
Hello,I would like to program the STM32 to control the circuit SAA1064 by I2C, using the STM32cubeIDE and HAL functions (HAL_I2C_Mem_Write,HAL_I2C_Master_Transmit, HAL_I2C_IsDeviceReady). then with the function "HAL_I2C_IsDeviceReady" shows that : th...
