RE: HELP ADC issue

Here is a version of above using HAL.

Set up g_adc0 on ADC Diver on r_adc in the configurator:

• ICU:
  • ADC0_SCAN_END = Priority 4
  • ADC0_SCAN_END_B = Priority 4
• Module:
  • Name = g_adc0
  • Unit = 0
  • Resolution = 12-Bit
  • Alignment = Right
  • Clear after read = ON
  • Mode = Single Scan
  • Channel Scan Mask :
    • Channel 0 = Use in Normal/Group A
    • Rest of channels = unused
• Rest of parameters all default

Code:

void process_divert_thread_entry(void)
{
ssp_err_t err;
adc_data_size_t testData;

err = g_adc0.p_api->open(g_adc0.p_ctrl, g_adc0.p_cfg); // confirmed SSP_SUCCESS

while (1)
{
err = g_adc0.p_api->scanStart(g_adc0.p_ctrl);
tx_thread_sleep (1); // let scan complete = more than enough time !!!
err = g_adc0.p_api->read(g_adc0.p_ctrl, ADC_REG_CHANNEL_0, &testData ); // NOTE 1.5 v measured on channel AN000
tx_thread_sleep (10);
}

// confirmed SSP_SUCCESS in all HAL steps above
// testData always reads 0

I do not understand why this does not work either ???

Thanks for your help,
