About I2C communication using STM32WL. STM32WLを使用�?��?�I2C通信�?��?��?��?�。
I want to use RTC (RX-8571) for I2C communication with STM32WLE5JC. I wrote the code using [HAL_I2C_Master_Transmit] and [HAL_I2C_Master_Receive], but I can only send the device address of the first byte. The errata says "Write the first data in I2C_...
Resolved! STM32CubeMX , how to live with it
I'm trying to set configuration for STM32WL55JC but I have no luck at all. I have set some pins, namely inputs: PB1,PC6,PC13, outputs: PB10,11,15, pc3,4,5, but the problem is all the time, I'm trying to not to touch almost anything wht is not needed...
Battery percentage level varying often for each uplink when b-l072z-lrwan1 board powered with batteries.
Running " i-cube-lrwan - End node" firmware on board. We are expecting consistent battery percentage but observing inconsistent in battery percentage. e.g. At first when battery is fully charged, it should show 100%. Later on as battery started drain...
Where to connect the arm ULINK plus on the board for power measurement?
Hi, I am not so sure about where to connect the jumpers from the ULINK plus on my STM32WL55JC board to measure power consumption? Can anyone please help? The picture of the board is from the UM2592 User Manual. I couldnt find the information.Thanks!

Can BLE connection slave latency > 0 allow a connection event to be skipped even if there is data to send?
This is the behavior I currently observe.I Send data at fixed intervals, but if i set slave latency to 1, than from time to time, i will have short periods of misses, the data arrives +- 1 connection event. If i set slave latency to 0, the data arriv...
