RE: Can I use nRF24L01+ with pic? is there any library?

Håkon Alseth — Thu, 22 Aug 2013 12:20:54 GMT

We do not have any libraries that are directly usable with PIC uC's, but we have a nrf_hal library which is included in the nRFgo SDK: ..\Nordic Semiconductor\nRFgo SDK 2.3.0.10040\source_code\hal\nrf24l01p ..\Nordic Semiconductor\nRFgo SDK 2.3.0.10040\source_code\hal\nrf24le1

The files you are interested in are: hal_nrf.c hal_nrf.h hal_nrf_reg.h

Files that needs porting: hal_nrf_hw.c hal_nrf_hw.h

Notes on hal_nrf.c: Functions "hal_nrf_read_multibyte_reg" and "hal_nrf_write_multibyte_reg" must be modified as they include 8051 memory type pointers.


  if (memtype == 0x00U)
  {
    const uint8_t data *buf = (const uint8_t data *)pbuf;
    NRF_WRITE_MULTIBYTE_REG_COMMON_BODY
  }
  else if (memtype == 0x01U)
  {
    const uint8_t xdata *buf = (const uint8_t xdata *)pbuf;
    NRF_WRITE_MULTIBYTE_REG_COMMON_BODY
  }
  else if (memtype == 0xFEU)
  {
    const uint8_t pdata *buf = (const uint8_t pdata *)pbuf;
    NRF_WRITE_MULTIBYTE_REG_COMMON_BODY
  }
  else
  {
    const uint8_t *buf = (const uint8_t *)pbuf;
    NRF_WRITE_MULTIBYTE_REG_COMMON_BODY
  }

  
if (memtype == 0x00U)
  {
    uint8_t data *buf = (uint8_t data *)pbuf;
    NRF_READ_MULTIBYTE_REG_COMMON_BODY
  }
  else if (memtype == 0x01U)
  {
    uint8_t xdata *buf = (uint8_t xdata *)pbuf;
    NRF_READ_MULTIBYTE_REG_COMMON_BODY
  }
  else if (memtype == 0xFEU)
  {
    uint8_t pdata *buf = (uint8_t pdata *)pbuf;
    NRF_READ_MULTIBYTE_REG_COMMON_BODY
  }
  else
  {
    uint8_t *buf = (uint8_t *)pbuf;
    NRF_READ_MULTIBYTE_REG_COMMON_BODY
  }

Basically, you want the last "else" to be executed.

When these files are copied/ported you should also be able to run projects like "enhanched_shockburst" with some porting.
