If you have any idéas, please respond. The actual sym file genertion seems best done with tragesym or djsymbox, but I need to find the pin number to pin name mapping. For that I could grab an ibis file, use pybis [1] or ibis.pl [2]. The problem with that is that some pins might be missing and it doesn't show alternate pin function names (think mcu's). I'm trying to find some way to take a table from a pdf and filter it through something that genererate a "pin" file. Then one could use that pin file, order it to ones liking (e.g. a separate power symbol, a big sym with all pins etc.), and then run tragesym/djsymbox. So this is about finding and generating something like pin type label 1 pas VSS ... for each package of the device. /// Copy and paste method. By marking the first page in the table (table 4, page 24..29 of [3]) in xpdf and copy to a text file I get: TRACECLK/ FSMC_A23 / - - 1 1 1 A2 PE2 I/O FT PE2 ETH_MII_TXD3 / EVENTOUT TRACED0/FSMC_A19/ - - 2 2 2 A1 PE3 I/O FT PE3 EVENTOUT TRACED1/FSMC_A20 / - - 3 3 3 B1 PE4 I/O FT PE4 DCMI_D4/ EVENTOUT TRACED2 / FSMC_A21 / - - 4 4 4 B2 PE5 I/O FT PE5 TIM9_CH1 / DCMI_D6/ EVENTOUT TRACED3 / FSMC_A22 / - - 5 5 5 B3 PE6 I/O FT PE6 TIM9_CH2 / DCMI_D7/ EVENTOUT 1 A9 6 6 6 C1 VBAT S VBAT Which looks parsable.

The data was taken from page device 24..28 stm32f100 (low/mid density) [3] 24..29 stm32f100 (high density) [4] 26..30 stm32f105/7 [5] 40..51 stm32f205 [6] Running pins_st32f100.pl (from [7]) on thoose files generated nice pin files (I added the first three lines, file prefix, package name, empty line; put a line with "//\n" to signal to the program where there is a page break, i.e. where column widths might change): $ head -15 st32f100h.tbl st32f100h LQFP144 LQFP100 LQFP64 1 1 - PE2 I/O FT PE2 TRACECK/ FSMC_A23 2 2 - PE3 I/O FT PE3 TRACED0/FSMC_A19 3 3 - PE4 I/O FT PE4 TRACED1/FSMC_A20 4 4 - PE5 I/O FT PE5 TRACED2/FSMC_A21 5 5 - PE6 I/O FT PE6 TRACED3/FSMC_A22 6 6 1 VBAT S VBAT PC13-TAMPER- 7 7 2 I/O PC13(6) TAMPER-RTC RTC(5) PC14- 8 8 3 I/O PC14(6) OSC32_IN OSC32_IN(5) $ head st32f100h.lqfp144.pins 1 pas* PE2 (FSMC_A23 TRACECK) 2 pas* PE3 (FSMC_A19 TRACED0) 3 pas* PE4 (FSMC_A20 TRACED1) 4 pas* PE5 (FSMC_A21 TRACED2) 5 pas* PE6 (FSMC_A22 TRACED3) 6 pwr VBAT 7 pas PC13 (TAMPER_RTC) 8 pas PC14 (OSC32_IN) 9 pas PC15 (OSC32_OUT) 10 pas* PF0 (FSMC_A0) Since the i/o pins could be both digital or analogue, I set the type to "pas" ("*" == 5V tolerant pin, should we define new pin types?). Except for stm32f205/7 where many more table cells are multiline, and I got bogus results like: $ grep -C2 '^11 G8 18 29 35 M5' st32f205_7.tbl SPI2_MOSI / I2S2_SD / OTG_HS_ULPI_NXT / ADC123_ 11 G8 18 29 35 M5 PC3(6) I/O FT PC3 ETH_MII_TX_CLK/ IN13 EVENTOUT $ grep '^ 29' st32f205_7.lqfp144.pins 29 pas* PC3 (ADC123_ ETH_MII_TX_CLK EVENTOUT I2S2_SD IN13 OTG_HS_ULPI_NXT SPI2_MOSI) $ where the ADC123_ should be joined with IN13.
