Bonjour Shibby,

Merci pour votre lien. à propos de ma langue j'ai des lacunes en Anglais mais qu'en meme je vais essayer. Le document contenu dans le lien comprend un menu qui doit etre affiché par l'Hyperterminal. Mon problème c'est de trouver la connexion necessaire avec la liaison RS232 pour pouvoir afficher le menu.

Cordialement.

Merci bien Shibby,

C'est vraiment c'est ce que je cherche. Je vais réaliser ce circuit (comprenant le MAX232). Je crois bien qu'elle va marcher. En tout cas je vais vous répondre après le test.

Merci

Hello FrankL,

Thank you for your answer. I'm also not good in English but i will try to understand you. I would like to inject in the microcontroller in-cicuit a .hex or .bin program. This will be realised with the assistance of BootLoader via a serial communication (RS232).This is my general idea. Concerning the FDT i'm not sure if  it necessite to use a programmer like E8 or Flasher of Renesas, or simply we can use it via a serial communicarion (RS232) knowing that the size of the hex file is smaller than 256 byte ????

Thank you FrankL,

There is another "problem": to communicate the microcontroller with the PC via the RS232, what are the necessary pins of the micro that must be connected except the Tx, Rx, Gnd and Vcc pins ???? i don't know if the CNVSS, RESET ... Pins must be connected or no,  if so what are their equivalent of pins in the serial cable.????

Thanks.

until now i understand how to use Rx, Tx and Gnd of the serial cable. But i don't know how to use CNVSS, P55 and P50. Besides the proposal cicuit of the M16C-Flasher i don't understand it. Thank you to explain me more about how to connect the pins of the serial cable to the pins of the micro and how use the M16-Flasher to inject a .hex file on the micro.

Thank you.

what about the pin "reset"  before and when programming the micro ?

Thank you Frank,

After testing different connections, the micro emits an ambiguous signal. I still have a little  doubt concerning the connection between the different pins . This link contain the electrical schematic of the carte containing the micro.http://dc197.4shared.com/download/238964136/a3d26eec/100989999-4a_SCM_CS7002_.pdf?tsid=20100311-083657-79782011http://www.4shared.com/dir/21897660/4a671fc9/sharing.html

Please send me the necessary connections (circuit) that i must realise it to program my micro.

Notes: The module IC3 is the micro, i will acced to the Pins of the micro by the connector 19.

Thanks a lot.
