Why the use of ST's Middlewares is soo haaaaard? STM32WLE5 CMSIS DSP LoRa

lemke.a.w · ‎2024-04-30

I'm trying to use the DSP Library on the STM32WLE5CCU6 and some error messages appear on STM32CubeIDE. I have the same code tested and running on STM32F103C8T6 and STM32F407VET6 without any problem.

STM32CubeIDE Version: 1.14.0 Build: 19471_20231121_1200 (UTC)

STM32CubeMX Version 6.10.0

STM32CubeWL Firmware Package v1.3.0 / 09-November-2022

STMicroelectronics.X-CUBE-ALGOBUILD DSP Library Library 1.3.0

I'm seriously thinking about switching to using any other STM32 with an external SX1262 chip via SPI interface than the STM32WL with its related libraries. The LoRa middleware is impossible to work with, I am forced to provide an UART interface (Why not use SWV / ITM interface ?) and the ADC , I cannot disable it.

This kind of thing sometimes makes me think about giving up on ST!

Could it be related to the STM32WLE5 not having FPU?

Yes Indeed. Glad to know that the problem is fixed.
