Hello,We need to use RS-485 in full duplex, and with the flow control (DE).Is it that when we configure DE with RS485 is shall be used as half duplex ?can I configure rs232 pins with RTS (instead of DE) before converting voltage to rs-485 levels ?Wil...
Posted on April 06, 2018 at 16:43 Hai, Iam using the STM32H743VIT controller , We are using the spi4 in our board ,we generated the code using the cube mx nothing is coming(CLK and SIN)when transmit the data using the function ( HAL_SPI_Transmit(SP...
sir, i am using STM32F4- discovery board, i want to configure color display with driver ST7735S. i want to know that how will i configure my spi to send data to the display. also the Nss pin.
Hi guys and girls!I'm using STSPIN32F0, an MCU with built-in 3-phase motor driver and I'm trying to read internal temperature sensor. What I'm getting back looks to me like random walk within range of about 10 degrees Celsius (please see attachment)....
We use STM32412 for our battery operated system.A strange case is observed where MCU stopped responding.Neither it got powered up, also seems the code was not being executed.Our NRST pin is powered by the same source by which MCU is powered, so NRST ...
Hi,I dont know whats wrong with my code, I just want to test the timer's working .the purpose of the program is to turn off the led after a number of cycle . but this have never been happen, the led still on.PS im working wit HSI_VALUE ((uint32_t)16...
I have a firmware of STM32F4 in IAR-EW IDE and now I would like to port this firmware to other STM32 controller and want to use TrueStudio IDE. So, @Community Members, Can you give the steps to do it? So, it will be easy for me to do it.
I have 7 adc channel must be measured. 4 channels are continuously measured by dma and adc 1, 3 of them are very important measured in special moment. I want to mesured this channels by injected channel adc2. my code for this as follow, but I can not...
I've been trying to get an STM32L031 to periodically wakeup with minimal power consumption. The specs say it can standby at under 0.5 µA, which I can confirm, but also that it can wake up within 65 µs, which I cannot reproduce. I'm seeing a 1.6 ms de...
