Function Documentation
◆ GPIOs_configure()
| void GPIOs_configure | ( | int | gpio_num, |
| enum gpio_mode | config | ||
| ) |
Configure one GPIO with the input config
- Parameters
-
config is configuration of type gpio_mode gpio_num is GPIO number it can have values from 0 to 37
- Note
- These configurations will not be change the GPIOs modes until calling GPIOs_loadConfigs()
◆ GPIOs_configureAll()
| void GPIOs_configureAll | ( | enum gpio_mode | config | ) |
Configure all GPIOs with the config
- Parameters
-
config is configuration of type gpio_mode
- Note
- These configurations will not be change the GPIOs modes until calling GPIOs_loadConfigs()
◆ GPIOs_loadConfigs()
| void GPIOs_loadConfigs | ( | ) |
Load the configurations changes to the GPIOs
◆ GPIOs_readHigh()
| unsigned int GPIOs_readHigh | ( | ) |
Read the highest 6 GPIOs GPIOS[37:32]
- Note
- For Reading value from the GPIOs, the GPIO should be configured as management input. otherwise 0 would be read
◆ GPIOs_readLow()
| unsigned int GPIOs_readLow | ( | ) |
Read low 32 GPIOs GPIOS[31:0]
- Note
- For Reading value from the GPIOs, the GPIO should be configured as management input. otherwise 0 would be read
◆ GPIOs_waitHigh()
| void GPIOs_waitHigh | ( | unsigned int | data | ) |
wait over the highest 6 GPIOs to equal the data passed
- Note
- For writing by this function to be seen at the GPIO the GPIO has to be configured as management output
- Parameters
-
data is the data that should wait until sent to the GPIOs
Examples:
- GPIOs_waitHigh(0x1); // function would return only when GPIO [32]==1 and rest of 5 GPIOs = 0
- GPIOs_waitHigh(0x5); // function would return only when GPIO [32]==1 and GPIO [34]==1 and rest of 4 GPIOs = 0
◆ GPIOs_waitHighWithMask()
| void GPIOs_waitHighWithMask | ( | unsigned int | data, |
| unsigned int | mask | ||
| ) |
wait over the masked highest 6 GPIOs to equal the data passed
- Note
- For writing by this function to be seen at the GPIO the GPIO has to be configured as management output
- Parameters
-
data is the data that should wait until sent to the GPIOs mask mask over the each GPIO if the mask value is 0 the this GPIO value are ignored
Examples:
- GPIOs_waitHighWithMask(0x1,0xF); // function would return only when GPIO [32]==1 and GPIO [35:33]==0 and don't care about the rest of GPIOs
- GPIOs_waitHighWithMask(0x5,0x7); // function would return only when GPIO [32]==1 and GPIO [34]==1 and GPIO [33]==0 and don't care about the rest of GPIOs
◆ GPIOs_waitLow()
| void GPIOs_waitLow | ( | unsigned int | data | ) |
wait over the lowest 32 GPIOsto equal the data passed
- Note
- For writing by this function to be seen at the GPIO the GPIO has to be configured as management output
- Parameters
-
data is the data that should wait until sent to the GPIOs
Examples:
- GPIOs_waitLow(0x1); // function would return only when GPIO [0]==1 and rest of 31 GPIOs= 0
- GPIOs_waitLow(0x5); // function would return only when GPIO [0]==1 and GPIO [3]==1 and rest of 30 GPIOs = 0
◆ GPIOs_waitLowWithMask()
| void GPIOs_waitLowWithMask | ( | unsigned int | data, |
| unsigned int | mask | ||
| ) |
wait over the masked lowest 32 GPIOs to equal the data passed
- Note
- For writing by this function to be seen at the GPIO the GPIO has to be configured as management output
- Parameters
-
data is the data that should wait until sent to the GPIOs mask mask over the each GPIO if the mask value is 0 the this GPIO value are ignored
Examples:
- GPIOs_waitLowWithMask(0x1,0xF); // function would return only when GPIO [0]==1 and GPIO [3:1]==0 and don't care about the rest of GPIOs
- GPIOs_waitLowWithMask(0x5,0x7); // function would return only when GPIO [0]==1 and GPIO [3]==1 and GPIO [2]==0 and don't care about the rest of GPIOs
◆ GPIOs_writeHigh()
| void GPIOs_writeHigh | ( | unsigned int | data | ) |
Write to the highest 6 GPIOs GPIOS[37:32]
- Note
- For writing by this function to be seen at the GPIO the GPIO has to be configured as management output
- Parameters
-

Examples:
- GPIOs_writeHigh(0x1); // write 1 to GPIO [32] and write 0 in the remaining 5 GPIOs
- GPIOs_writeHigh(0x5); // write 1 to GPIO [32] and 34 and write 0 in the remaining 4 GPIOs
◆ GPIOs_writeLow()
| void GPIOs_writeLow | ( | unsigned int | data | ) |
Write to the low 32 GPIOs GPIOS[31:0]
- Note
- For writing by this function to be seen at the GPIO the GPIO has to be configured as management output
