Hello,
i'am trying to control the pwm Idle State Level.
between my Sequence's (1sek) the PIN stays High But i need it low.
I try to set the GPIO Out Register, but this didn't work.
uint32_t seq0_ram[9]= {0x80198019,0x80108010,0x80198019,0x80148014,0x80148014,0x00140014,0x00140014,0x00140014,0xFF};
uint32_t b = NRF_GPIO->OUT;
NRF_GPIO->OUT = (b &~0x100000);
NRF_PWM0->PSEL.OUT[0] = (first_pin << PWM_PSEL_OUT_PIN_Pos) |
(PWM_PSEL_OUT_CONNECT_Connected <<
PWM_PSEL_OUT_CONNECT_Pos);
NRF_PWM0->ENABLE = (PWM_ENABLE_ENABLE_Enabled << PWM_ENABLE_ENABLE_Pos);
NRF_PWM0->MODE = (PWM_MODE_UPDOWN_Up << PWM_MODE_UPDOWN_Pos);
NRF_PWM0->PRESCALER = (PWM_PRESCALER_PRESCALER_DIV_1 <<
PWM_PRESCALER_PRESCALER_Pos);
NRF_PWM0->COUNTERTOP = (27 << PWM_COUNTERTOP_COUNTERTOP_Pos); //1 msec
NRF_PWM0->LOOP = (PWM_LOOP_CNT_Disabled << PWM_LOOP_CNT_Pos);
NRF_PWM0->DECODER = (PWM_DECODER_LOAD_Common << PWM_DECODER_LOAD_Pos) |
(PWM_DECODER_MODE_RefreshCount << PWM_DECODER_MODE_Pos);
NRF_PWM0->SEQ[0].PTR = ((uint32_t)(seq0_ram) << PWM_SEQ_PTR_PTR_Pos);
NRF_PWM0->SEQ[0].CNT = ((sizeof(seq0_ram) / sizeof(uint16_t)) <<
PWM_SEQ_CNT_CNT_Pos);
NRF_PWM0->SEQ[0].REFRESH = 0;
NRF_PWM0->SEQ[0].ENDDELAY = 100;
NRF_PWM0->TASKS_SEQSTART[0] = 1;
