STM8S003F3 ADC single scan mode

[vinodstanur]

Hi,
recently I started playing with stm8s microcontroller, I am using stm8s003f3 microcontroller.
I am planning to use SCAN MODE in adc. From the datasheet it seems like scan mode can happen only from ADC0 to ADCn where n is the channel number.

Single scan mode.
This mode is used to convert a sequence of analog channels from AIN0 to AINn where ‘n’ is
the channel number defined by the CH[3:0] bits in the ADC_CSR register. During the scan
conversion sequence the CH[3:0] bits are updated by hardware and contain the channel
number currently being converted.

But in the stm8s003f3 the ADC channel numbering starts from ADC2. (ADC2 to ADC6 (5 channels))
So I am a bit confused how to configure the SCAN mode channel limit settings.

Hi,

Same for me. I'm validating my design with the "STM8S Value Line Discovery" which is implemanted with a STM8S003K3. It has ADC inputs from CH0 to 3.
I'm now wondering if my scan mode will work well when I'll switch to STM8S003F3 with CH2 to CH5... :-?
Did you already try this feature?

Hi...vinodstanur,

I am planning to start with STM8S003F3, so can you please tell me from where i can get that discovery kit...

and about how much its costly??......which compiler for it we can use, specially with 'C' language..??



Regards,

Regards,

I bought it from element14, the stm8s discovery board. But it is not STM8S003F3, it is having a better 8s with more flash and RAM. But I am using the discovery as a programmer and debugger for STM8S003F3 in my custom board.

Compiler I am using is cosmic, which is a thirdparty compiler which U can integrate to the IDE STVD from ST.

Vinodstanur,

If I need to design simple development board of stm8s...can you please help/guide me for its basic circuit(I.e as we generally seen in case of 8051/PIC/AVR like.. crystal ckt, reset ckt, programming pins like MOSI,MISO, DATA, PGM,VCC,GND or any EP pin to vcc or gnd etc)
