[En-Nut-Discussion] Enabling ADC on EIR

[Ulrich Prinz]

Hi!

Search for the cpu definitions in conf/arch/arch.conf
Every CPU has a provides section where it provides its features.

            {
                macro = "MCU_AT91SAM7SE32",
                brief = "Atmel AT91SAM7SE32",
                 description = "ARM7TDMI 16/32-bit RISC microcontroller 
with 32K bytes flash, "..
                     "8K bytes RAM, external bus interface, USB, 2 
USARTs and more. ",
                flavor = "boolean",
                exclusivity = mcu_names,
                file = "include/cfg/arch.h",
                requires = { "TOOL_CC_ARM" },
                provides = {
                    "HW_TARGET",
                    "HW_MCU_ARM",
                    "HW_MCU_AT91",
                    "HW_MCU_AT91SAM7SE",
                    "HW_TIMER_AT91",
                    "HW_PLL_AT91",
                    "HW_SDRAMC",
                    "HW_PIT_AT91",
                    "HW_UART_AT91",
                    "HW_DBGU_AT91",
                    "HW_UART0_RTSCTS",
                    "HW_UART1_RTSCTS",
                    "HW_UART1_MODEM",
                    "HW_SPI_AT91",
                    "HW_TWI_AT91",
                    "HW_RSTC_AT91",
                    "HW_PDC_AT91",
                    "HW_EFC_AT91",
                    "HW_GPIO",
                    "HW_EBI_AT91"
                },
                makedefs = { "MCU=arm7tdmi" }


Now add "HW_ADC_AT91" to any CPU that works with this driver you wrote.

Modify the "requires = {}" statement in the arm.nut to "HW_ADC_AT91" 
and you have your desired result, are compatible to the design and you 
can provide a patch file for us to implement it into the official 
trunk. There is no problem if you cannot identify any valid cpu, we can 
check that.

Best Regards
Ulrich

Hi folks, I use the ADC Funktion on EIR. The ADC on EIR is implemented, 
working and tested by me. Unfortanatelly the ADC is disabled on the EIR 
Hardware. I'm enabling the  function with the following hack in the 
arm.nut conf file: Old:  {        name = "nutarch_arm_adc_at91",        
brief = "AT91 ADC",        description = "ADC interface for AT91 
(currently SAM7 only).",        requires = { "HW_MCU_AT91SAM7X" },    
<-------------------------------------------XXXXX        provides = { 
"DEV_ADC" },        sources = { "arm/dev/at91_adc.c" },    },    My 
hack:     {        name = "nutarch_arm_adc_at91",        brief = "AT91 
ADC",        description = "ADC interface for AT91 (currently SAM7 
only).",        requires = { "HW_MCU_AT91SAM7SE" },    
<-----------------------------------------XXXXX        provides = { 
"DEV_ADC" },        sources = { "arm/dev/at91_adc.c" },    },     Now 
my question: Can anyone modify the conf-file, so that it is possible to 
enable the ADC on EIR? Perhaps Harald? I have no idea to modify 
conf-Files. Does anyone have an documentation about this?Thank you and 
best regardsJörg
