Dear sir,

Could you tell me if I can delete some part when I just want to program ST7F MCU? because it is difficult for me to get some part.

Best Regards,

Could you be a bit more specific ?

Hi SJO,

Do you have plans to support ST5 ?

I have started adding ST5 support to Flashbash, and as soon as I receive some flash samples I will complete the support.

The hardware requires no changes - just a firmware update.

Regards

SJO

Now I am making a prototype programmer with you provide the PCB and schematic. One point I want to confirm: because I don't have ST232A on hand, I just have ST232, but in your schematic you use ST232A, so could you tell me if I can use ST232 to replace ST232A?

as I know, the speed of ST232A is higher than ST232.

Looking forward your response! Thank your support.

You can use any of the ST232 range, the only reason I use the A is for lower power consumption.

I have just updated Flashbash - device support added for ST72FLITE10,15,19 and ST72FMC. SUPERLITE range changed to ST7FLITES2/ST7FLITES5.

Reset delay feature added for differant reset circuits.

Flashbash can now be used with the st72f264 aswell as the 254. Firmware upgrade via the serial port is available with the 264.

Modified schematics using the 264 sci have also been added.

Dear sjo

Can FLASHBASH be used for manufactory programming just like segger flash programming tools?

you know segger also use serial port for programming. Have you compared the programming speed

of FLASHBASH with ST7xxx-EPB programming tools?

dear sjo,

I have problem about ICP: as you know there is no need of isolation

about ICCDATA and ICCCLK pin if these two pin is configured as output(decribed in the data sheet). But if I solder a blank chip on the board and begin to program with ICP and there are two LED connected with these two pin(include two 680ohm series resister. But I found I can not program the chip with ICP mode by using ST7-STICK. what is the problem? can I use FLASHBASH to program?

best regards,

How con I implement a branch table in inline assembly with Metrowerks C compiler? Following code doesn't work :

asm{

...

LD X,Nerx

SLL X ; X <- Nerx * 2

LD A,(TB_GRAF_RX+1,X)

PUSH A ; MSB of return @

LD A,(TB_GRAF_RX,X)

PUSH A ; LSB of return @

RET

; Branch to subroutine (TB_GRAF_RX + 2*Nerx)

TB_GRAF_RX:

DC graf_rx_0, graf_rx_1, graf_rx_2 ,graf_rx_3

DC graf_rx_4, graf_rx_5, graf_rx_6 ,graf_rx_7

graf_rx_0:

...

graf_rx_1:

...

and so on...
