Hi all, I'm trying to implement SPI TX communication with DMA. The following "prepareDMASPI()" function should configure and start DMA transferts from a buffer to the SPI device. But it doesn't work (No spi clock or MOSI data), although the SPI is pr...

Hi, I have a Nucleo-wl55jc2 (US Low Band 433 Mhz) Would it be possible to remove the RF filters so I can run it on high frequences (EU 868 Mhz) ? Thanks Olivier

I bought NUCLEO-WL5JC2 Low Band (As NUCLEO-WL5JC1 were not in stock)Is it possible to turn them into High Band by changing some passive components ? So I can use them in 868Mhz instead of 433Mhz Thanks

Hi all. I found out there are specific DEBUG_SUBGHZSPI_* alternate functions (DS13105 STM32WLE5xx). But there is not much information about these functions. Can these AF be used to 'mirror' SUBGHZSPI pins for debugging / captures ? Thanks Olivier...

Hi all. I'd like to write a simple bare-metal application for STM32WLE5JC. Could you provide snippet code for STM32WL (core + radio) initialization and simple RX/TX Lora Packet ? Thanks Olivier

Hi, So stupid .... You were right : I forgot to enable clock The above code is now working, as soon as you add the clock enable at the beginning of the function !// Enable DMA/DMAMUX clocks stm32.RCC.AHB1ENR.SetBits(stm32.RCC_AHB1ENR_DMAMUX1EN | stm3...

By the way, I'd like ton know what would appends if I bypass the LC filters and I connect RFO_LP/RFO_HP to BGS13S4N9 RF Switch.Thx for your help

Hi Mecanix. Actually, you should have a look to my port of STM32WLE5 (and its sx126x radio) for TinyGO (Still Work in progress)Right now, this project is suspended because of some major change in TinyGO's internal timer management ... But some parts...

Hi Mecanix. Sorry, but I did not manage to write a simple code for STM32WLE5. But I'm still interested a some stripped down example for sending Lora packet if someone have it .Olivier

Seeed LORA-E5 is great, but there are only a limited number of STM32WL pins routed on the module.
