I'm using PWM with level shifter(BSS138, 74HCT14D, TXB0104) for developing IC embedded LED (such as WS2812) However, when I captured this siganl using scope, I found that the signal was not clear.Below are the pictures that I captured. 1. Before addi...
Hello,I have been working on creating an SPI loop using the SPI callback function to alternate between two sensors that share a common SPI SDI/SDO line. However, I am encountering an issue where the SPI transfer complete callback is triggered, but t...
Dear Team,We are currently in the process of selecting components for our project, and we have identified the STM32U5A5QJ9(STM32U5A5QJ , foot-print size UFBGA 132 7x7x0.6 P 0.5 mm) microcontroller as a potential candidate. However, upon reviewing th...
Hi Team,I am reaching out to inquire about the availability of the reference design for the STM32U5A5QJI6Q microcontroller We are currently in the process of designing a project that could greatly benefit from utilizing this specific microcontrolle...
hi, I am beginner for ARM controller bootloader development. I am using STM32F103C8T6 controller. so, how to merge bootloader and application hex files. I am using STM32 Cube IDE for development. kindly help to me. if you have any bootloader develop...
Hi.I am using STM32H7B3LIH MCU and Newhaven "NHD-4.3-800480CF-ASXP" TFT. I completed all the configuration according to the instructions in AN4861. I am trying to show an 800x480 image on the screen using framebuffer. I use "LCD image converter" to c...
Hi,I cannot understand acquired ADC data order using this configuration on a STM32G030C6 device:I want to acquire 9 input channels + 2 internal channels (Temperature Sensor + Vbat). Continuous mode w/ Circular DMAHere's my Initialization routine stat...
II am using the SPI function in STM32F373R8T6. When I use the HAL_SPI_TransmitReceive function to send and receive data, I want the to read the data from the slave immediately after sending. However, when using this function, the NSS pin pulls up fo...
Hi, I have been using an STM32F405RGT6 in a design for a the last ~5 years and am investigating a problem where the bootloader has stopped working at some point in production. Our design started with the 'Y' revision of the chip and previously used S...
I need to make a "multi threaded" application, my mentor told me this, and I quote "you should create a thread by yourselfuse any system timer, e.g. simple tick timer"I do not really understand this, but he gave me some example pseudocode, hopefully ...
