This is a big and somewhat tough problem. I'm not familiar with the RAK module. I can't tell from the schematic which STM32 is being used. See my comments on #61 about possibility (3) -- you have to be using the right BSP. Our BSP does not define PB13, etc, so I'm pretty sure you're not using ours. I'm afraid that, based on experience with timing problems with the code in stm32duino-based releases, I have no resources to help with other BSPs right now. If you want to try to add support for the RAK to our board support package, we will definitely accept a pull request.
Basic recommendations:
Good luck! --Terry
Hi
I am trying to make this library work with the RAK811 module, but I can not find the correct configuration, I think my problem is in the definition and use of the pins
RADIO_RF_CRX_RX PB_6 //CRF3 (ANT_SWITCH_TX_BOOST) RADIO_RF_CBT_HF PB_7 //CRF2 HF (ANT_SWITCH_TX_RFO) RADIO_RF_CTX_PA PA_4 //CRF1 PA (ANT_SWITCH_RX)
// LORA
define RADIO_RESET_PORT PB13
define RADIO_MOSI_PORT PA7
define RADIO_MISO_PORT PA6
define RADIO_SCLK_PORT PA5
define RADIO_NSS_PORT PB0
define RADIO_DIO_0_PORT PA11
define RADIO_DIO_1_PORT PB1
define RADIO_DIO_2_PORT PA3
define RADIO_DIO_3_PORT PH0
define RADIO_DIO_4_PORT PC13
//#define RADIO_DIO_5_PORT PA4
define RADIO_RF_CRX_RX PB_6 //CRF3 (ANT_SWITCH_TX_BOOST)
define RADIO_RF_CBT_HF PB_7 //CRF2 HF (ANT_SWITCH_TX_RFO)
define RADIO_RF_CTX_PA PA_4 //CRF1 PA (ANT_SWITCH_RX)
define RADIO_XTAL_EN PH_1
My Pin mapping
const lmic_pinmap lmic_pins = { .nss = RADIO_NSS_PORT, .rxtx = RADIO_RF_CRX_RX, .rst = RADIO_RESET_PORT, .dio = {RADIO_DIO_0_PORT, RADIO_DIO_1_PORT, RADIO_DIO_2_PORT}, // the RAK811 module needs D29 high for RX, low for TX. //.rxtx_rx_polarity = 1 .rxtx_rx_active = 0, // the Murata module is direct-wired, we can use 8 MHz for SPI. .spi_freq = 8000000 };
