I'm developing a low-power device using the STM32WLE5.To reduce power consumption of the peripherals (sensors / display / eeprom) during the sleep of the MCU, all these peripherals are switched off with a P-channel mosfet as shown in this part of the...
Resolved! RF transmit power on STM32WB with Zigbee stack
Hello,The datasheet for STM32WB55RG (DS11929, 3.6.1 RF front-end block diagram, page 22) states that the output power is user programmable:"In Transmit mode, the maximum output power is user selectable through the programmable LDO voltage of the powe...
Resolved! Pairing STM32WB55 with Windows with no IO capabilities
Hi, I am trying to pair STM32WB55 (slave) with windows (master) on a custom setup. While pairing, I am getting this error. The STM32WB55 must have no IO capabilities, and hence configured as No Input No Output. This seems to show that authentication ...
STM32WL55J sharing ADC and SWJ-DP
Hi, For a project I need 12 ADCs. STM32WL55JCU6 has all the necessary ADCs but two of them are shared with SWDIO and SWCLK pins. Is there any good suggestion for being able to use both these functions at the same time?
Resolved! STM32WL5x: Undocumented Bug in IRTIM Module
Hello,I have been developing a program on the NUCLEO-WL55JC1 development board, and I found a bug in the IRTIM module. The reference manual says that, when enabled, the IRTIM module will NAND the outputs of TIM16 and TIM17 and output the signal on a ...
