Hello E2E support team,
I have several ADC pins on my board and I need to read the measurements (temperature and voltage). I describe my ADC in the PinMUX, but when I generate am43xx_pinmux_data.c there is NO information about ADC at all. When I look at the provided examples for the IDK_AM437x board:
C:\ti\pdk_am437x_1_0_14\packages\ti\starterware\board\am43xx\am43xx_idkevm_pinmux_data.c
There I can see ADC pins in the provided C code!!!
Here is how I describe my ADC pins:
I tried both ONLINE and OFFLINE tools, but the result is the same - NO pins generated for ADC!
Here is the snippet of the generated code:
pinmuxBoardCfg_t gAm437xPinmuxData[] =
{
#if defined(BUILDCFG_MOD_UART)
{CHIPDB_MOD_ID_UART, gUartPinCfg},
#endif /* if defined(BUILDCFG_MOD_UART) */
#if defined(BUILDCFG_MOD_PRU_ICSS)
{CHIPDB_MOD_ID_PRU_ICSS, gPru_icssPinCfg},
#endif /* if defined(BUILDCFG_MOD_PRU_ICSS) */
#if defined(BUILDCFG_MOD_I2C)
{CHIPDB_MOD_ID_I2C, gI2cPinCfg},
#endif /* if defined(BUILDCFG_MOD_I2C) */
#if defined(BUILDCFG_MOD_CPSW)
{CHIPDB_MOD_ID_CPSW, gCpswPinCfg},
#endif /* if defined(BUILDCFG_MOD_CPSW) */
#if defined(BUILDCFG_MOD_MMCSD)
{CHIPDB_MOD_ID_MMCSD, gMmcsdPinCfg},
#endif /* if defined(BUILDCFG_MOD_MMCSD) */
#if defined(BUILDCFG_MOD_QSPI)
{CHIPDB_MOD_ID_QSPI, gQspiPinCfg},
#endif /* if defined(BUILDCFG_MOD_QSPI) */
#if defined(BUILDCFG_MOD_GPIO)
{CHIPDB_MOD_ID_GPIO, gGpioPinCfg},
#endif /* if defined(BUILDCFG_MOD_GPIO) */
#if defined(BUILDCFG_MOD_RTC)
{CHIPDB_MOD_ID_RTC, gRtcPinCfg},
#endif /* if defined(BUILDCFG_MOD_RTC) */
{CHIPDB_MOD_ID_INVALID}
};
No ADC pins listed!
How can I read all my available ADC signals?
How many ADC chips on the board? If I have 7 pins with analog signals should I somehow multiplex these signal to the single ADC chip?
"starterware\examples\adc\volt_measure" doesn't really make it clear how to read many channels.
Thank you! Any help will be very appreciated!
