Hi Winfred,
I create switch based board to select commands on nucleo board. I'v got 5 switches:
1 - init S2LP registers,
2 - check MC_State's,
3 - send frame (send fifo bytes and tx strobe),
4 - set SDN pin,
5 - reset SDN pin.
Now the first sequence: 4,5,1,3,2 and the board stuck with MC_State0 = 0xE9 (atachment 1-BAD.jpg is the voltage on VrSynth). Then I do the same sequence (board have still a power supply) and then the board work good and the MC_State0 = 0x01 (in the TX_Sent isr arrived), the voltage in Vrsynth look's rising faster(2-good.jpg).
The init sequence:
SRadioInit xRadioInit = {
BASE_FREQUENCY,
MODULATION_SELECT,
DATARATE,
FREQ_DEVIATION,
BANDWIDTH
};
PktBasicInit xBasicInit={
PREAMBLE_LENGTH,
SYNC_LENGTH,
SYNC_WORD,
VARIABLE_LENGTH,
EXTENDED_LENGTH_FIELD,
CRC_MODE,
EN_ADDRESS,
EN_FEC,
EN_WHITENING
};
SGpioInit xGpioIRQ={
S2LP_GPIO_1,
S2LP_GPIO_MODE_DIGITAL_OUTPUT_HP,
S2LP_GPIO_DIG_OUT_IRQ
};
uint8_t status_arr[4];
void Init_S2LP_TX(void)
{
S2LPPktBasicSetPayloadLength(20);
S2LPGpioIrqDeInit(NULL);
S2LPPktBasicInit(&xBasicInit);
S2LPRadioInit(&xRadioInit);
S2LPGpioInit(&xGpioIRQ);
S2LPGpioIrqConfig(MAX_RE_TX_REACH,S_ENABLE);
S2LPGpioIrqConfig(TX_DATA_SENT,S_ENABLE);
S2LPPktBasicSetPayloadLength(20);
}ISR:
void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){
if(GPIO_Pin==IRQ_SENT_Pin)
{
S2LPGpioIrqGetStatus(&xIrqStatus);
if(xIrqStatus.IRQ_TX_DATA_SENT == S_SET || xIrqStatus.IRQ_MAX_RE_TX_REACH == S_SET)
{
xTxDoneFlag = RESET;
HAL_GPIO_WritePin(LEDR_GPIO_Port,LEDR_Pin,RESET);
}
else
{}
}
}task:
if(cmd[0] == '1')
{Init_S2LP_TX();
S2LPSpiReadRegisters(0x8e, 1, statusr);
cmd[0]=0;}
if(cmd[0] == '2')
{S2LPSpiReadRegisters(0x8e, 1, statusr);
cmd[0]=0;}
if(cmd[0] == '3'){
flag = 1;
xTxDoneFlag = RESET;
cmd[0]=0;}
if(cmd[0] == '4'){
HAL_GPIO_WritePin(RESET_RF_GPIO_Port, RESET_RF_Pin, GPIO_PIN_SET);
cmd[0]=0;}
if(cmd[0] == '5'){
HAL_GPIO_WritePin(RESET_RF_GPIO_Port, RESET_RF_Pin, GPIO_PIN_RESET);
cmd[0]=0;}
if(xTxDoneFlag == RESET) // If an ISR read TX_Sent == SET
{
S2LPCmdStrobeFlushTxFifo();
vTaskDelay(10/portTICK_RATE_MS);
S2LPSpiWriteFifo(20, radio_frame);
HAL_GPIO_WritePin(LD2_GPIO_Port,LD2_Pin,SET);
S2LPCmdStrobeTx();
vTaskDelay(10/portTICK_RATE_MS);
xTxDoneFlag = SET;
vTaskDelay(10/portTICK_RATE_MS);
}As you see here is a difference with load cap time and the shape for a first run.
Here is a second start:
Thank for a replay.
