TIMx_RCR IRQ?
I am using TIM16 as a one second counter on an STM32WB55. I would like to generate an interrupt after it rolls x times (as example 2). I set the TIMx_RCR to a 1. Can someone tell me what function I need to call in the HAL library and should I plac...
STMWLE5CC (RAK3172) Radio End-of-life flag not correctly resetting
Greetings, i am developing a application that will run on a RAK3172 module and i have been attempting to use the radio End-Of-Life flag to detect when the battery supply is too depleted to operate the radio safely.The base application is the LoRaWAN_...
Hi all, I want to develop a framework using LoRa and LoRaWAN and send the data to The Things Network.
I have already done it, but I want to change the code for the P-NUCLEO-LRWAN3gateway. Is it possible to share the code if you have it?I use the bin file for the gateway and the expansion code for the end-devices.Board used: https://www.st.com/en/eva...
Resolved! I can't run or debug my CM0+ with NUCLEO-WL55JC1.
I have no problem to flash or debug the CM4 of the board. But when I'm trying to flash the CM0+ this error occurred : Error in final launch sequence:Failed to start GDB serverFailed to start GDB serverError in initializing ST-LINK device.Reason: (255...
How can I increase ADC measuring speed? and which part can cause a delay?
I'm using the necleo-wb55 board.I'm trying to increase ADC measuring speed but I found that the speed for 16-bit measurement and 12-bit measurement looks the same even though 16-bit uses 256 oversampling. I checked how many measuring cycles happen us...
120mA current consumption when supply external 3V3 power - Nucleo-WL55JC1 (CN6)
When you power Nucleo-WL55JC! with external 3V3 via CN6, I could see constant 120mA current consumption. Is there any way we can reduce this?
