Hi. I need to have the value of 2 channels and the internal temperature. My adc is setup as this: hadc.Instance = ADC1; hadc.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV1; hadc.Init.Resolution = ADC_RESOLUTION_12B; hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc.Init.ScanConvMode = ADC_SCAN_DIRECTION_FORWARD; hadc.Init.EOCSelection =… Show more
We are using STM8L051F3 and it has 2 inputs which is 2 key keypad which we are using for our application. Now i want to use that keypad for ON/OFF of microcontroller also.How i can do that? I want to ON controller power supply when i press keypad key and then i will use those key for my application also and then if i key for long time or press… Show more
It is how you want. Modern micro-controllers do not need to remove power. The current consumption in sleep mode is very small. A wake up the controller can be executed by the same button, connecting it to the wake up input signal. 2018-01-20 6:55 GMT+02:00 Omkar Teli <email@example.com>: STMicroelectronics Community…
Hello, i am using STM32F429IIT controller.I am trying communicate between CAN1 and CAN2 but yet not success.can you please provide any reference code for the CAN communication. Thanks
You should get an example going first with a CAN-dongle. I used the CanDo unit, made it transmit every 10mS and worked on my receiver first. Using HAL drivers and examples, sets 'your' code aside from the 'processor' code. It is the best methodology if you want transportable code. but if you want to use the direct method, this will only work…
Hi, Trying to get I2C communication between a F334 and a 24C32 EEPROM working, The read and write functions do return correctly, but the reads do not match what has been written to the EEPROM. Struggling to find the issue at hand and in the thought that someone could possibly lend me a hand on this issue, which would be very helpful. The… Show more
Hi, I have configured accelerometer's registers as follows. So, from the activity threshold value how I know that at which raw value of X, Y, and Z axis it will be interrupted on a specific pin? /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// response… Show more
Hello. I was working with the LRWAN software using the Murata module a couple of months ago and was happy with its operation and functionality on my custom PCB. I moved over to hardware/antenna development and now have a board whose performance I am happy with. However I have now moved back into software development and noticed that the… Show more

Hi everyone, I'm working with a LIS3DH accel and having trouble reading registers. I'm able to successfully read the value from any single register, but all subsequent reads return the same value. I.e. if I read WHO_AM_I register, and then read CTRL_REG1, both read commands return the value from the WHO_AM_I register. Has anyone encountered… Show more
Dear All, I have just ported the RTOS uKOS (www.ukos.ch) on the new stm32H743. Everything work fine at the exception of the usart2. I have strange situations with the interruptions, and as soon as I receive a character in the interruption handle, I have a crash machine (hard fault). It is tricky and difficult to figure out what is the real… Show more
Today in one of my projects I've enabled a new feature of my RTOS (distortos - advanced real-time operating system) which ensures some functions are not used in interrupts. This checks - among others - for any use of mutexes from interrupts, as it is a logical error to do that (first of all - interrupts cannot "block" and additionally using… Show more

I am looking for a GUI window in Keil uvision4 to send data to the serial. When I open serial window (USART #1-3), I am not able to type any characters on the screen to send to the serial. Is there a way to manually type data that will be seen by the simulating environment (uvision) as having been received on the serial port?
