I'm trying to implement the workaround for PAN58 on an nRF52832 device using SDK15.2
I've copied in the code from a previous post but I keep getting an error when I declare 'NRF_SPIM_Type * p_spim = TCspi.p_registers;' in the set up. The error I get says 'nrf_drv_spi_t {aka const struct <anonymous>}' has no member named 'p_registers'.
Init code is included. What am I doing wrong?
void Init_TC_SPI(void) {
ret_code_t ret;
// Configure SPIM-0 for TFT operation
nrf_drv_spi_config_t spi_config = NRF_DRV_SPI_DEFAULT_CONFIG;
spi_config.ss_pin = SPIM_CS;
spi_config.miso_pin = SPIM_MISO;
spi_config.mosi_pin = SPIM_MOSI;
spi_config.sck_pin = SPIM_CLK;
spi_config.mode = NRF_DRV_SPI_MODE_1;
spi_config.frequency = NRF_DRV_SPI_FREQ_4M;
// APP_ERROR_CHECK(nrf_drv_spi_init(&spi, &spi_config, spi_event_handler, NULL));
ret = nrf_drv_spi_init(&TCspi, &spi_config, spi_event_handler, NULL);
//ret = nrf_drv_spi_init(&TCspi, &spi_config, NULL, NULL);
//if(ret!=NRFX_SUCCESS) { SET_ERR(w9_SPI_init_failed);}
// ### Workaround Section Start ###
uint32_t err_code;
NRF_SPIM_Type * p_spim = TCspi.p_registers;
//NRF_SPIM_Type * p_spim = TCspi.p_reg;
//Initialize GPIOTE and PPI drivers for the workaround
err_code = nrf_drv_gpiote_init();
APP_ERROR_CHECK(err_code);
// Initializes the GPIOTE channel so that SCK toggles generates events
nrf_drv_gpiote_in_config_t config = GPIOTE_CONFIG_IN_SENSE_TOGGLE(true);
err_code = nrf_drv_gpiote_in_init(SPIM_CLK, &config, in_pin_handler);
APP_ERROR_CHECK(err_code);
err_code = nrf_drv_ppi_init();
APP_ERROR_CHECK(err_code);
// Allocate first unused PPI channel
err_code = nrf_drv_ppi_channel_alloc(&ppi_channel);
APP_ERROR_CHECK(err_code);
// Assign the PPI channel to the SCK pin
err_code = nrf_drv_ppi_channel_assign(ppi_channel,
nrf_drv_gpiote_in_event_addr_get(SPIM_CLK),
(uint32_t)&p_spim->TASKS_STOP);
APP_ERROR_CHECK(err_code);
// ### Workaround Section End ###
