Hi, I'm currently trying to use ADC 1 peripheral on RM48L952 but it seems to be stuck on busy.
adcData_t testAdc;
_enable_interrupt_();
_mpuInit_();
_mpuEnable_();
adcInit();
adcEnableNotification(adcREG1, adcGROUP1);
adcStartConversion(adcREG1, adcGROUP1);
while(!adcIsConversionComplete(adcREG1, adcGROUP1));
adcGetData(adcREG1, adcGROUP1, &testAdc);
Looking at registers it seems to be ok but the program is stuck at while(!adcIsConversionComplete(adcREG1, adcGROUP1));.
A point to note is that my device has only AD1IN[0] connected and ADREFHI, ADREFLO, AD1EVT are not, just trying to see if adc peripheral works. I think that's not the problem but it might be worth noting.
Also ADC1 Group 1 in VIM channel is not enabled.
Here is adc group 1 setting. I haven't tinkered sample timing.
Below is some registers at waiting loop.
R MibAdc1_OpModeCtrl 0x0000000B 0x81140001 // 12 bit, adc enabled
R MibAdc1_G1ModeCtrl 0x0000000B 0x00000000 // software triggered, oneshot
R MibAdc1_G1IntEna 0x0000000B 0x00000008 // conversion end interrupt enabled
R MibAdc1_G1IntFlg 0x0000000B 0x00000004 // memory empty
R MibAdc1_EvSr 0x0000000B 0x00000008
R MibAdc1_G1Sr 0x0000000B 0x0000000C // memory is empty and busy

R MibAdc1_G2Sel 0x0000000B 0x00000000
